precision Issues?

Hi again :-)

I give openmap a center co-ord (lat and lon ) and a scale ( got via ProjMath ) and the center i get back is not the same... is out a little...

using proj.getUpperLeft() and proj.getLowerRight() methods.. this is my situation

ask for centre -157.23015 lon 21.38713 lat
and get centre -157.23013 lon 21.387129 lat

obviously different requests gather different levels of errors... im wondering whats causing this. My math is all Float, and seems good to me ... perhaps its what OM depends on in calculating its bits? or a deg-rad problem?...
