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
