    minabs

    NPM version Build Status Coverage Status dependencies

    Return the minimum absolute value.

    Installation

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

    Usage

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

    minabs( [x[, y[, ...args]]] )

    Returns the minimum absolute value.

    var v = minabs( -4.2, 3.14 );
    // returns 3.14
    
    v = minabs( +0.0, -0.0 );
    // returns +0.0
    
    v = minabs( 4.2, 3.14, -1.0, 6.8 );
    // returns 1.0

    If any argument is NaN, the function returns NaN.

    var v = minabs( 4.2, NaN );
    // returns NaN
    
    v = minabs( NaN, 3.14 );
    // returns NaN

    If not provided any arguments, the function returns +infinity.

    var v = minabs();
    // returns Infinity

    Notes

    • When an empty set is considered a subset of the extended reals (all real numbers, including positive and negative infinity), positive infinity is the greatest lower bound. Similar to zero being the identity element for the sum of an empty set and to one being the identity element for the product of an empty set, positive infinity is the identity element for the minimum, and thus, minabs() = +infinity.

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var minabs = require( '@stdlib/math-base-special-minabs' );
    
    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 = minabs( x, y );
        console.log( 'minabs(%d,%d) = %d', x, y, v );
    }

    Notice

    This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
