FLOAT64_MIN_SAFE_INTEGER

Minimum safe double-precision floating-point integer.

Installation

npm install @stdlib/constants-float64-min-safe-integer

Alternatively,

• To load the package in a website via a script tag without installation and bundlers, use the ES Module available on the esm branch.
• If you are using Deno, visit the deno branch.
• For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the umd branch.

The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.

Usage

var FLOAT64_MIN_SAFE_INTEGER = require( '@stdlib/constants-float64-min-safe-integer' );

FLOAT64_MIN_SAFE_INTEGER

The minimum safe double-precision floating-point integer.

var bool = ( FLOAT64_MIN_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_MIN_SAFE_INTEGER = require( '@stdlib/constants-float64-min-safe-integer' );

var min;
var x;
var i;

min = -pow( 2.0, 55 );
for ( i = 0; i < 100; i++ ) {
    x = round( randu() * min );
    if ( x < FLOAT64_MIN_SAFE_INTEGER ) {
        console.log( 'Unsafe: %d', x );
    } else {
        console.log( 'Safe: %d', x );
    }
