var randu = require( '@stdlib/random-base-randu' );
var maxabs = require( '@stdlib/math-base-special-maxabs' );

var x;
var y;
var v;
var i;

for ( i = 0; i < 100; i++ ) {
    x = ( randu()*1000.0 ) - 500.0;
    y = ( randu()*1000.0 ) - 500.0;
    v = maxabs( x, y );
    console.log( 'maxabs(%d,%d) = %d', x, y, v );
