Arbitrary precision? As in automatically increasing precision to stay exact? You will find this impractical as the number of decimals will explode, or you will find it not at all. If you mean that you want to be able to select something with larger precision than single or double floats, numpy is the starting point. > >Appreciate any comments. > >Ken Groetjes Albert -- -- Albert van der Horst, UTRECHT,THE NETHERLANDS Economic growth -- being exponential -- ultimately falters. albert@spe&ar&c.xs4all.nl &=n http://home.hccnet.nl/a.w.m.van.der.horst -- http://mail.python.org/mailman/listinfo/python-list
