Package Exports

@stdlib/math-base-special-minmaxabs
@stdlib/math-base-special-minmaxabs/lib/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@stdlib/math-base-special-minmaxabs) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

minmaxabs

$NPM version$ $Build Status$ $Coverage Status$

Return the minimum and maximum absolute values.

Installation

npm install @stdlib/math-base-special-minmaxabs

Usage

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

minmaxabs( [out,] x[, y[, ...args]] )

Returns the minimum and maximum absolute values in a single pass.

var v = minmaxabs( 4.2, 3.14 );
// returns [ 3.14, 4.2 ]

v = minmaxabs( +0.0, -0.0 );
// returns [ 0.0, 0.0 ]

v = minmaxabs( 4.2, 3.14, -1.0, -6.8 );
// returns [ 1.0, 6.8 ]

If any argument is NaN, the function returns NaN for both the minimum value and the maximum value.

var v = minmaxabs( 4.2, NaN );
// returns [ NaN, NaN ]

v = minmaxabs( NaN, 3.14 );
// returns [ NaN, NaN ]

By default, the function returns minimum and maximum absolute values as a two-element array. To avoid unnecessary memory allocation, the function supports providing an output (destination) object.

var Float64Array = require( '@stdlib/array-float64' );

var out = new Float64Array( 2 );

var v = minmaxabs( out, 5.0, 3.0, -2.0, 1.0 );
// returns <Float64Array>[ 1.0, 5.0 ]

var bool = ( v === out );
// returns true

Examples

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

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

for ( i = 0; i < 100; i++ ) {
    x = ( randu()*100.0 ) - 50.0;
    y = ( randu()*100.0 ) - 50.0;
    v = minmaxabs( x, y );
    console.log( 'minmaxabs(%d,%d) = [%d, %d]', x, y, v[0], v[1] );
}
