exp10(3)

exp103

Base-10 exponential function

Usage

#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);

Library

Math library (libm, -lm)

Overview

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).

Errors

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