\fIinterp\fR. The slave interpreter is identified by \fIslaveName\fR.
If no such slave interpreter exists, \fBNULL\fR is returned.
.PP
\fBTcl_GetMaster\fR returns a pointer to the master interpreter of
\fIinterp\fR. If \fIinterp\fR has no master (it is a
top-level interpreter) then \fBNULL\fR is returned.
.PP
\fBTcl_GetInterpPath\fR stores in the result of \fIinterp\fR
the relative path between \fIinterp\fR and \fIslaveInterp\fR;
\fIslaveInterp\fR must be a slave of \fIinterp\fR. If the computation
of the relative path succeeds, \fBTCL_OK\fR is returned, else
\fBTCL_ERROR\fR is returned and an error message is stored as the
result of \fIinterp\fR.
.PP
\fBTcl_CreateAlias\fR creates a command named \fIslaveCmd\fR in
\fIslaveInterp\fR that when invoked, will cause the command \fItargetCmd\fR
to be invoked in \fItargetInterp\fR. The arguments specified by the strings
contained in \fIargv\fR are always prepended to any arguments supplied in the
invocation of \fIslaveCmd\fR and passed to \fItargetCmd\fR.
This operation returns \fBTCL_OK\fR if it succeeds, or \fBTCL_ERROR\fR if

.AP Tcl_DString *dsPtr in/out
Pointer to structure that is used to manage a dynamic string.
.AP "const char" *bytes in
Pointer to characters to append to dynamic string.
.AP "const char" *element in
Pointer to characters to append as list element to dynamic string.
.AP size_t length in
Number of bytes from \fIbytes\fR to add to dynamic string.  If TCL_INDEX_NONE,
add all characters up to null terminating character.
.AP size_t newLength in
New length for dynamic string, not including null terminating
character.
.AP Tcl_Interp *interp in/out
Interpreter whose result is to be set from or moved to the
dynamic string.

the two procedures return \fBTCL_OK\fR after appending the values.
.PP
\fBTcl_NewListObj\fR and \fBTcl_SetListObj\fR
create a new value or modify an existing value to hold
the \fIobjc\fR elements of the array referenced by \fIobjv\fR
where each element is a pointer to a Tcl value.
If \fIobjc\fR is less than or equal to zero,
they return an empty value. If \fIobjv\fR is NULL, the resulting list
contains 0 elements, with reserved space in an internal representation
for \fIobjc\fR more elements (to avoid its reallocation later).
The new value's string representation is left invalid.
The two procedures increment the reference counts
of the elements in \fIobjc\fR since the list value now refers to them.
The new list value returned by \fBTcl_NewListObj\fR
has reference count zero.
.PP
\fBTcl_ListObjGetElements\fR returns a count and a pointer to an array of

\fBTcl_ConcatObj\fR(\fIobjc, objv\fR)
.SH ARGUMENTS
.AS "const Tcl_UniChar" *appendObjPtr in/out
.AP "const char" *bytes in
Points to the first byte of an array of UTF-8-encoded bytes
used to set or append to a string value.
This byte array may contain embedded null characters
unless \fInumChars\fR is TCL_INDEX_NONE.  (Applications needing null bytes
should represent them as the two-byte sequence \fI\e300\e200\fR, use
\fBTcl_ExternalToUtf\fR to convert, or \fBTcl_NewByteArrayObj\fR if
the string is a collection of uninterpreted bytes.)
.AP size_t length in
The number of bytes to copy from \fIbytes\fR when
initializing, setting, or appending to a string value.
If TCL_INDEX_NONE, all bytes up to the first null are used.
.AP "const Tcl_UniChar" *unicode in
Points to the first byte of an array of Unicode characters
used to set or append to a string value.
This byte array may contain embedded null characters
unless \fInumChars\fR is negative.
.AP size_t numChars in
The number of Unicode characters to copy from \fIunicode\fR when
initializing, setting, or appending to a string value.
If TCL_INDEX_NONE, all characters up to the first null character are used.
.AP size_t index in
The index of the Unicode character to return.
.AP size_t first in
The index of the first Unicode character in the Unicode range to be
returned as a new value.
.AP size_t last in
The index of the last Unicode character in the Unicode range to be

The hexadecimal digits \fIhhhhhhhh\fR (one up to eight of them) give a
twenty-one-bit hexadecimal value for the Unicode character that will be
inserted, in the range U+000000\(enU+10FFFF.  The parser will stop just
before this range overflows, or when the maximum of eight digits
is reached.  The upper bits of the Unicode character will be 0.
.RS
.PP
The range U+00D800\(enU+00DFFF is reserved for surrogates, which
are illegal on its own. Therefore, such sequences will result in
the replacement character U+FFFD. Surrogate pairs should be
encoded as single \e\fBU\fIhhhhhhhh\fR character.

Backslash substitution is not performed on words enclosed in braces,
except for backslash-newline as described above.

.AP size_t count in
The maximum number of bytes to get from the stream, or TCL_INDEX_NONE to get
all remaining bytes from the stream's buffers.
.AP Tcl_Obj *compDict in
A byte array value that is the compression dictionary to use with the stream.
Note that this is \fInot a Tcl dictionary\fR, and it is recommended that this
only ever be used with streams that were created with their \fIformat\fR set
to \fBTCL_ZLIB_FORMAT_ZLIB\fR because the other formats have no mechanism to

.PP
Given \fIsrc\fR, a pointer to some location in a UTF-8 string,
\fBTcl_UtfNext\fR returns a pointer to the next UTF-8 character in the
string.  The caller must not ask for the next character after the last
character in the string if the string is not terminated by a null
character.

\fBTcl_UtfPrev\fR is used to step backward through but not beyond the
UTF-8 string that begins at \fIstart\fR.  If the UTF-8 string is made

to the lead byte of one of those characters (or to the location one byte
past the end of the string), then repeated calls of \fBTcl_UtfPrev\fR will
return pointers to the lead bytes of each character in the string, one
character at a time, terminating when it returns \fIstart\fR.
.PP
When the conditions of completeness and well-formedness may not be satisfied,
a more precise description of the function of \fBTcl_UtfPrev\fR is necessary.
It always returns a pointer greater than or equal to \fIstart\fR; that is,
always a pointer to a location in the string. It always returns a pointer to
a byte that begins a character when scanning for characters beginning
from \fIstart\fR. When \fIsrc\fR is greater than \fIstart\fR, it
always returns a pointer less than \fIsrc\fR and greater than or
equal to (\fIsrc\fR - \fBTCL_UTF_MAX\fR).  The character that begins
at the returned pointer is the first one that either includes the
byte \fIsrc[-1]\fR, or might include it if the right trail bytes are
present at \fIsrc\fR and greater. \fBTcl_UtfPrev\fR never reads the
byte \fIsrc[0]\fR nor the byte \fIstart[-1]\fR nor the byte
\fIsrc[-\fBTCL_UTF_MAX\fI-1]\fR.
.PP
\fBTcl_UniCharAtIndex\fR corresponds to a C string array dereference or the
Pascal Ord() function.  It returns the Unicode character represented at the
specified character (not byte) \fIindex\fR in the UTF-8 string
\fIsrc\fR.  The source string must contain at least \fIindex\fR
characters.  If \fIindex\fR is TCL_INDEX_NONE or \fIindex\fR points
to the second half of a surrogate pair, it returns -1.
.PP
\fBTcl_UtfAtIndex\fR returns a pointer to the specified character (not
byte) \fIindex\fR in the UTF-8 string \fIsrc\fR.  The source string must
contain at least \fIindex\fR characters.  This is equivalent to calling
\fBTcl_UtfToUniChar\fR \fIindex\fR times.  If \fIindex\fR is TCL_INDEX_NONE,
the return pointer points to the first character in the source string.
.PP
\fBTcl_UtfBackslash\fR is a utility procedure used by several of the Tcl
commands.  It parses a backslash sequence and stores the properly formed
UTF-8 character represented by the backslash sequence in the output

.SH NAME
expr \- Evaluate an expression
.SH SYNOPSIS
\fBexpr \fIarg \fR?\fIarg arg ...\fR?
.BE
.SH DESCRIPTION
.PP
The \fIexpr\fR command concatenates \fIarg\fRs, separated by a space, into an expression, and evaluates
that expression, returning its value.
The operators permitted in an expression include a subset of
the operators permitted in C expressions.  For those operators
common to both Tcl and C, Tcl applies the same meaning and precedence
as the corresponding C operators.
The value of an expression is often a numeric result, either an integer or a
floating-point value, but may also be a non-numeric value.

value is the form produced by the \fB%g\fR format specifier of Tcl's
\fBformat\fR command.
.SS OPERANDS
.PP
An expression consists of a combination of operands, operators, parentheses and
commas, possibly with whitespace between any of these elements, which is
ignored.














.PP
An operand may be specified in any of the following ways:
.IP [1]
As a numeric value, either integer or floating-point.
.IP [2]
As a boolean value, using any form understood by \fBstring is\fR
\fBboolean\fR.

\fBexpr\fR {{word one} < "word $a"}	\fI0\fR
.CE
.PP
\fBInteger value\fR
.PP
An integer operand may be specified in decimal (the normal case, the optional
first two characters are \fB0d\fR), binary
(the first two characters are \fB0b\fR), octal
(the first two characters are \fB0o\fR), or hexadecimal
(the first two characters are \fB0x\fR) form.  For
.PP
\fBFloating-point value\fR
.PP
A floating-point number may be specified in any of several
common decimal formats, and may use the decimal point \fB.\fR,
\fBe\fR or \fBE\fR for scientific notation, and
the sign characters \fB+\fR and \fB\-\fR.  The
following are all valid floating-point numbers:  2.1, 3., 6e4, 7.91e+16.
The strings \fBInf\fR
and \fBNaN\fR, in any combination of case, are also recognized as floating point
values.  An operand that doesn't have a numeric interpretation must be quoted
with either braces or with double quotes.
.PP
\fBBoolean value\fR
.PP
A boolean value may be represented by any of the values \fB0\fR, \fBfalse\fR, \fBno\fR,
or \fBoff\fR and any of the values \fB1\fR, \fBtrue\fR, \fByes\fR, or \fBon\fR.
.PP
\fBDigit Separator\fR
.PP
Digits in any numeric value may be separated with one or more underscore
characters, "\fB_\fR", to improve readability.  These separators may only
appear between digits.  The separator may not appear at the start of a
numeric value, between the leading 0 and radix specifier, or at the
end of a numeric value.  Here are some examples:

.CE
.PP
.SS OPERATORS
.PP
For operators having both a numeric mode and a string mode, the numeric mode is
chosen when all operands have a numeric interpretation.  The integer
interpretation of an operand is preferred over the floating-point
interpretation.  To ensure string operations on arbitrary values it is generally a
good idea to use \fBeq\fR, \fBne\fR, or the \fBstring\fR command instead of

indices will be in ascending numeric order. If values are returned, the order
of the values will be the order of those values within the input \fIlist\fR.
