complex-modulus

  

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]](#references) is:

!Complex modulus

Usage

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

Calculates |a + ib| and returns a number

Example

``javascript
var cmod = require('complex-modulus');

var result = cmod( 3, 4 );

// result = 5
``
