Absolute Difference

Compute the absolute difference of two real numbers.

The absolute difference of two real numbers is defined as the absolute value of their difference.

Absolute difference

Usage

var absdiff = require( '@stdlib/math/base/utils/absolute-difference' );

absdiff( x, y )

Computes the absolute difference of two real numbers.

var d = absdiff( 2.0, 5.0 );
// returns 3.0

d = absdiff( -1.0, 3.14 );
// returns ~4.14

d = absdiff( 10.1, -2.05 );
// returns ~12.15

d = absdiff( -0.0, 0.0 );
// returns +0.0

d = absdiff( NaN, 5.0 );
// returns NaN

d = absdiff( 5.0, NaN );
// returns NaN

d = absdiff( Infinity, Infinity );
// returns NaN

d = absdiff( -Infinity, -Infinity );
// returns NaN

d = absdiff( Infinity, -Infinity );
// returns Infinity

d = absdiff( -Infinity, Infinity );
// returns Infinity

Examples

var randu = require( '@stdlib/random/base/randu' );
var absdiff = require( '@stdlib/math/base/utils/absolute-difference' );

var x;
var y;
var d;
var i;

for ( i = 0; i < 100; i++ ) {
    x = (randu()*1.0e4) - 1.0e2;
    y = (randu()*1.0e4) - 1.0e2;
    d = absdiff( x, y );
    console.log( 'x = %d. y = %d. |x-y| = %d.', x, y, d );
}
