NAME

exp10, exp10f, exp10l - bas-10 exponential function

LIBRARY

Math library (libm,~-lm)

SYNOPSIS

#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);

DESCRIPTION

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

RETURN VALUE

On success, these functions return the bas-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. For a discussion of the errors that can occur for these functions, see exp(3).

ATTRIBUTES

For an explanation of the terms used in this section, see attributes(7).

HISTORY

glibc 2.1.

BUGS

Before glibc 2.19, the glibc implementation of these functions did not set errno to ERANGE when an underflow error occurred.
