// returns true

Examples

var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var pow = require( '@stdlib/math-base-special-pow' );
var FLOAT64_MAX_SAFE_INTEGER = require( '@stdlib/constants-float64-max-safe-integer' );

var max;
var x;
var i;

max = pow( 2.0, 55 );
for ( i = 0; i < 100; i++ ) {
    x = round( randu() * max );
    if ( x > FLOAT64_MAX_SAFE_INTEGER ) {
        console.log( 'Unsafe: %d', x );
    } else {
        console.log( 'Safe: %d', x );
    }
