# isfinitef
> Test if a single-precision floating-point numeric value is finite.
## Usage
```javascript
var isfinitef = require( '@stdlib/math/base/assert/is-finitef' );
```
#### isfinitef( x )
Tests if a single-precision floating-point `numeric` value is finite.
```javascript
var bool = isfinitef( 3.14 );
// returns true
bool = isfinitef( Infinity );
// returns false
bool = isfinitef( -Infinity );
// returns false
bool = isfinitef( NaN );
// returns false
```
## Examples
```javascript
var PINF = require( '@stdlib/constants/float32/pinf' );
var NINF = require( '@stdlib/constants/float32/ninf' );
var isfinitef = require( '@stdlib/math/base/assert/is-finitef' );
var bool = isfinitef( 5.0 );
// returns true
bool = isfinitef( -2.0e32 );
// returns true
bool = isfinitef( PINF );
// returns false
bool = isfinitef( NINF );
// returns false
bool = isfinitef( NaN );
// returns false
```
