Minimum safe double-precision floating-point integer.

Package Exports

  • @stdlib/constants-float64-min-safe-integer

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/constants-float64-min-safe-integer) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Min Safe Integer

NPM version Build Status Coverage Status dependencies

Minimum safe double-precision floating-point integer.

Installation

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

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 );
    }
