Maptitude - http://research.umbc.edu/~roswell/maptitude.html
If you think the data might be causing this, multiply the floating point
numbers by 1,000 or 100,000 or whatever to get rid of the decimal point.
Do all of the processing, and at the end, divide your results by the same
factor. This way, Maptitude math will have to work only on integers.
