# isfinite

> Test if a double-precision floating-point numeric value is finite.

<section class="usage">

## Usage

```javascript
var isfinite = require( '@stdlib/math/base/assert/is-finite' );
```

#### isfinite( x )

Tests if a double-precision floating-point `numeric` value is finite.

```javascript
var bool = isfinite( 3.14 );
// returns true

bool = isfinite( Infinity );
// returns false

bool = isfinite( -Infinity );
// returns false

bool = isfinite( NaN );
// returns false
```

## Examples

<!-- eslint no-undef: "error" -->

```javascript
var PINF = require( '@stdlib/constants/float64/pinf' );
var NINF = require( '@stdlib/constants/float64/ninf' );
var isfinite = require( '@stdlib/math/base/assert/is-finite' );

var bool = isfinite( 5.0 );
// returns true

bool = isfinite( -2.0e64 );
// returns true

bool = isfinite( PINF );
// returns false

bool = isfinite( NINF );
// returns false

bool = isfinite( NaN );
// returns false
```
