Convert function to ruby, from either C or PHP

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. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
