Floating point complex division
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 is:
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.
var cdiv = ;var result = ;// result = [ 0.44, 0.08 ]
