exp10, exp10f, exp10l — base-10 exponential function


#define _GNU_SOURCE /* See feature_test_macros(7) */

#include <math.h>

double exp10(double x);

float exp10f(float x);

long double exp10l(long double x);

Link with -lm.


These functions return the value of 10 raised to the power of x.

Return Value

On success, these functions return the base-10 exponential value of x.

For various special cases, including the handling of infinity and NaN, as well as overflows and underflows, see exp(3).


See math_error(7) for information on how to determine whether an error has occurred when calling these functions.

For a discussion of the errors that can occur for these functions, see exp(3).


These functions first appeared in glibc in version 2.1.
