There is a function that converts map coords from NZMG to lat/long. The source for this function is available as both PHP here : [login to view URL] and in C here : [login to view URL][]=86&actionargs[]=22 NOTE: Ruby has a Complex library so writing the cadd etc functions is not needed. The function should be enclosed in a class for simple re-use The function should work with the test data: Input NZMG e,n: 2487100.638 6751049.719 Output Lat/Long: -34.444066 172.739194 Input NZMG e,n: 2486533.395 6077263.661 Output Lat/Long: -40.512409 172.723106 Input NZMG e,n: 2216746.425 5388508.765 Output Lat/Long: -46.651295 169.172062 ***OR*** Instead of porting the function to ruby, make a ruby c extension by wrapping the c code, and provide instructions to compile, install and use on linux.
