FLOAT16_SIGN_MASK

Mask for the sign bit of a half-precision floating-point number.

Installation

npm install @stdlib/constants-float16-sign-mask

Usage

var FLOAT16_SIGN_MASK = require( '@stdlib/constants-float16-sign-mask' );

FLOAT16_SIGN_MASK

Mask for the sign bit of a half-precision floating-point number.

// 0x8000 = 32768 => 1 00000 0000000000
var bool = ( FLOAT16_SIGN_MASK === 0x8000 );
// returns true

Examples

var toWord = require( '@stdlib/number-float16-base-to-word' );
var FLOAT16_SIGN_MASK = require( '@stdlib/constants-float16-sign-mask' );

var x = -11.5;
var w = toWord( x ); // 1 10010 0111000000
// returns 51648

// Mask off all bits except for the sign bit:
var out = (w & FLOAT16_SIGN_MASK)>>>0; // 1 00000 0000000000
// returns 32768

// Turn off the sign bit and leave other bits unchanged:
out = w & (~FLOAT16_SIGN_MASK); // 0 10010 0111000000
// returns 18880
