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
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 );
}
}
