NAME
       exp, log, log10,	pow - exponential, logarithmic and power functions

SYNOPSIS
       #include	<math.h>

       double exp(double x);

       double log(double x);

       double log10(double x);

       double pow(double x, double y);

DESCRIPTION
       The  exp()  function  returns the value of e (the base of natural loga-
       rithms) 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.

ERRORS
       The log() and log10() functions can return the following	errors:

       EDOM   The argument x is	negative.

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

       The pow() function can return the following error:

       EDOM   The argument x is	negative and y is not an integral value.  This
	      would result in a	complex	number.
