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

var bool = isInfinite( Infinity );
// returns true

bool = isInfinite( -Infinity );
// returns true

Examples

var PINF = require( '@stdlib/constants/float64/pinf' );
var NINF = require( '@stdlib/constants/float64/ninf' );
var isInfinite = require( '@stdlib/math/base/assert/is-infinite' );

var bool = isInfinite( PINF );
// returns true

bool = isInfinite( NINF );
// returns true

bool = isInfinite( 5.0 );
// returns false

bool = isInfinite( NaN );
// returns false
