EXP(3)              Linux Programmer's Manual              EXP(3)
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 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.
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.
