## Usage
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var isInfinitef = require( '@stdlib/math/base/assert/is-infinitef' );
|
||
|
|
```
|
||
|
|
|
||
|
|
#### isInfinitef( x )
|
||
|
|
|
||
|
|
Tests if a single-precision floating-point `numeric` value is infinite.
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var bool = isInfinitef( Infinity );
|
||
|
|
// returns true
|
||
|
|
|
||
|
|
bool = isInfinitef( -Infinity );
|
||
|
|
// returns true
|
||
|
|
```
