# pow10l(3)

base-10 power functions

Part of [pow10(3)](/pow10/3.md).

## NAME

pow10, pow10f, pow10l - base-10 power functions

## LIBRARY

Math library (*libm*, *-lm*)

## SYNOPSIS

```
#define _GNU_SOURCE         /* See feature_test_macros(7) */
#include <math.h>
```

**double pow10(double** *x***);** **float pow10f(float** *x***);** **long double pow10l(long double** *x***);**

## DESCRIPTION

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

**Note well**: These functions perform exactly the same task as the functions described in [**exp10**(3)](/exp10/3.md), with the difference that the latter functions are now standardized in TS 18661-4:2015. Those latter functions should be used in preference to the functions described in this page.
