<h3>EXP(3) Linux Programmer's Manual EXP(3)
</h3>
<h3>NAME
</h3> exp, log, log10, pow - exponential, logarithmic and power
functions
<h3>SYNOPSIS
</h3> #include <math.h>
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
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.
