EQUAL _ _ _ _ _ _ _ _ _ _ _ _ operator
The operator equal is an infix binary comparison operator. It is identical with =. It returns true if its two arguments are equal.
Equality is given between floating point numbers and integers that have the same value.
on rounded; a := 4; A := 4 b := 4.0; B := 4.0 if a equal b then write "true" else write "false"; true if a equal 5 then write "true" else write "false"; false if a equal sqrt(16) then write "true" else write "false"; true
Comparison operators can only be used as conditions in conditional commands such as if...then and repeat...until. <equal> can also be used as a prefix operator. However, this use is not encouraged.
