    hypot

    NPM version Build Status Coverage Status

    Compute the hypotenuse.

    Installation

    npm install @stdlib/math-base-special-fast-hypot

    Usage

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

    hypot( x, y )

    Computes the hypotenuse.

    var h = hypot( -5.0, 12.0 );
    // returns 13.0

    Notes

    • For a sufficiently large x and/or y, computing the hypotenuse will overflow.

      var h = hypot( 1.0e154, 1.0e154 );
      // returns Infinity

      Similarly, for sufficiently small x and/or y, computing the hypotenuse will underflow.

      var h = hypot( 1e-200, 1.0e-200 );
      // returns 0.0

    Examples

    var randu = require( '@stdlib/random-base-randu' );
    var round = require( '@stdlib/math-base-special-round' );
    var hypot = require( '@stdlib/math-base-special-fast-hypot' );
    
    var x;
    var y;
    var h;
    var i;
    
    for ( i = 0; i < 100; i++ ) {
        x = round( randu()*100.0 ) - 50.0;
        y = round( randu()*100.0 ) - 50.0;
        h = hypot( x, y );
        console.log( 'hypot(%d,%d) = %d', x, y, h );
    }
