FLOAT64_MAX_SAFE_INTEGER

Maximum safe double-precision floating-point integer.

Usage

var FLOAT64_MAX_SAFE_INTEGER = require( '@stdlib/constants/float64/max-safe-integer' );

FLOAT64_MAX_SAFE_INTEGER

The maximum safe double-precision floating-point integer.

var bool = ( FLOAT64_MAX_SAFE_INTEGER === 9007199254740991 );
// 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 );
    }
