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

Installation

npm install @stdlib/math-base-assert-is-finitef

Usage

var isfinitef = require( '@stdlib/math-base-assert-is-finitef' );

isfinitef( x )

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

var bool = isfinitef( 3.14 );
// returns true

bool = isfinitef( Infinity );
// returns false

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

bool = isfinitef( NaN );
// returns false

Examples

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
