sub

Subtract two half-precision floating-point numbers.

Installation

npm install @stdlib/number-float16-base-sub

Usage

var sub = require( '@stdlib/number-float16-base-sub' );

sub( x, y )

Subtracts two half-precision floating-point numbers.

var v = sub( -1.0, 5.0 );
// returns -6.0

v = sub( 2.0, 5.0 );
// returns -3.0

v = sub( 0.0, 5.0 );
// returns -5.0

v = sub( -0.0, 0.0 );
// returns -0.0

v = sub( NaN, NaN );
// returns NaN

Examples

var toFloat16 = require( '@stdlib/number-float64-base-to-float16' );
var uniform = require( '@stdlib/random-array-uniform' );
var map = require( '@stdlib/array-base-map' );
var logEachMap = require( '@stdlib/console-log-each-map' );
var sub = require( '@stdlib/number-float16-base-sub' );

var x = map( uniform( 100, -50.0, 50.0 ), toFloat16 );
var y = map( uniform( 100, -50.0, 50.0 ), toFloat16 );

logEachMap( 'x: %f, y: %f => %f', x, y, sub );
