# exp10

> Base `10` [exponential function][exponential-function].

<section class="usage">

## Usage

```javascript
var exp10 = require( '@stdlib/math/base/special/exp10' );
```

#### exp10( x )

Evaluates the base `10` [exponential function][exponential-function].

```javascript
var v = exp10( 3.0 );
// returns 1000.0

v = exp10( -9.0 );
// returns 1.0e-9

v = exp10( 0.0 );
// returns 1.0

v = exp10( NaN );
// returns NaN
```

var randu = require( '@stdlib/random/base/randu' );
var exp10 = require( '@stdlib/math/base/special/exp10' );

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = (randu()*100.0) - 50.0;
    console.log( '10^%d = %d', x, exp10( x ) );
}

### Usage

```c
#include "stdlib/math/base/special/exp10.h"
```

#### stdlib_base_exp10( x )

Evaluates the base `10` [exponential function][exponential-function].

```c
double out = stdlib_base_exp10( 3.0 );
// returns 1000.0

out = stdlib_base_exp10( -9.0 );
// returns 1.0e-9
```

The function accepts the following arguments:

-   **x**: `[in] double` input value.

```c
double stdlib_base_exp10( const double x );
```
