You might check out http://www.remotesensing.org/proj/ which has source and documentation for PROJ.4, map projection software. I think the source is in C and you would probably have to dig for the algorithms, unless they are in the documentation. Sorry but I haven't looked at PROJ.4 in a long time. I normally refer to a book by John Snyder, "Map Projections-- A Working Manual" which was published by USGS as "USGS Professional Paper 1395" in 1987. But that isn't online and I'm not sure it is available anymore.
