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:

Usage

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

Calculates |a + ib| and returns a number

Example

cmod = require('complex-modulus');

result = cmod( 3, 4 );

esult = 5
