exp, log, log10, pow − exponential, logarithmic and power functions
#include <math.h>
double exp(double 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. |
