&lt;m&gt; and &lt;n&gt; are positive integers. 
<em>scientific_notation</em> controls the output format of floating point 
numbers. At the default settings, any number with five or less digits 
before the decimal point is printed in a fixed-point notation, e.g., 
12345.6. Numbers with more than five digits are printed in scientific 
notation, e.g., 1.234567E+5. Similarly, by default, any number with 
eleven or more zeros after the decimal point is printed in scientific 
notation. 
<P>
<P>
When <em>scientific_notation</em> is called with the numerical argument 
 m a number with more than m digits before the decimal point, 
or m or more zeros after the decimal point, is printed in scientific 
notation. When <em>scientific_notation</em> is called with a list 
{&lt;m&gt;,&lt;n&gt;}, a number with more than m digits before the 
decimal point, or n or more zeros after the decimal point is 
printed in scientific notation.
