abs2

Compute the squared absolute value.

Usage

var abs2 = require( '@stdlib/math/base/special/abs2' );

abs2( x )

Computes the squared absolute value.

var v = abs2( -1.0 );
// returns 1.0

v = abs2( 2.0 );
// returns 4.0

v = abs2( 0.0 );
// returns 0.0

v = abs2( -0.0 );
// returns 0.0

v = abs2( NaN );
// returns NaN

Examples

var randu = require( '@stdlib/random/base/randu' );
var round = require( '@stdlib/math/base/special/round' );
var abs2 = require( '@stdlib/math/base/special/abs2' );

var x;
var i;

for ( i = 0; i < 100; i++ ) {
    x = round( randu() * 100.0 ) - 50.0;
    console.log( 'abs2(%d) = %d', x, abs2( x ) );
}
