Max Safe Integer

Maximum safe half-precision floating-point integer.

Installation

npm install @stdlib/constants-float16-max-safe-integer

Usage

var FLOAT16_MAX_SAFE_INTEGER = require( '@stdlib/constants-float16-max-safe-integer' );

FLOAT16_MAX_SAFE_INTEGER

The maximum safe half-precision floating-point integer.

var bool = ( FLOAT16_MAX_SAFE_INTEGER === 2047 );
// 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 FLOAT16_MAX_SAFE_INTEGER = require( '@stdlib/constants-float16-max-safe-integer' );

var max;
var x;
var i;

max = pow( 2.0, 13 );
for ( i = 0; i < 100; i++ ) {
    x = round( randu() * max );
    if ( x > FLOAT16_MAX_SAFE_INTEGER ) {
        console.log( 'Unsafe: %d', x );
    } else {
        console.log( 'Safe: %d', x );
    }
}
