Floating point complex modulus

Intro

Calculating a floating point complex modulus isn't quite trivial. The naive method may encounter overflow, underflow, or loss of precision due to the intermediate floating point results. A simple remedy[1] is:

Complex modulus

Usage

require('complex-modulus')( a, b )

Calculates |a + ib| and returns a number

Example

var cmod = require('complex-modulus');
 
var result = cmod( 3, 4 );
 
// result = 5
