EXP
NAME SYNOPSIS DESCRIPTION ERRORS CONFORMING TO SEE ALSO
exp, log, log10, pow - exponential, logarithmic and power functions
#include x); double log(double x); double log10(double x); double pow(double x, double y);
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.
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.
