Floating point complex division

Intro

Complex floating point division 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 division

Usage

require('complex-division')( a, b, c, d [, result] )

Calculates (a + ib)/(c + id) and returns a two-element JS array with the real and imaginary components.

result is an optional Array or typed array into which the output is inserted.

Example

var cdiv = require('complex-division');
 
var result = cdiv( 1, 2, 3, 4 );
 
// result = [ 0.44, 0.08 ]
