<h3>SYNOPSIS
</h3>       #include &lt;math.h&gt;

double exp(double x);

double log(double x);

double log10(double x);

double pow(double x, double y);

<h3>DESCRIPTION
</h3>       The exp() function returns the value of  e  (the  base  of
natural logarithms) raised to the power of x.

The log() function returns the natural logarithm of x.

The log10() function returns the base-10 logarithm of x.

The  pow()  function  returns the value of x raised to the
power of y.

<h3>ERRORS
</h3>       The log() and log10() functions can return  the  following

EDOM   The argument x is negative.

ERANGE The  argument  x  is  zero.  The log of zero is not
