    minmaxabs

    NPM version Build Status Coverage Status dependencies

    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] );
    }
