We have the gmpy module which can do arbitray precision floats. >>> gmpy.pi(600) mpf ('3.1415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679821480865132823066470938446095505822317253594081284811174502841027019385211055596446e0', 600) > > --Scott David Daniels > scott.dani...@acm.org -- http://mail.python.org/mailman/listinfo/python-list
