You want the kinds package, part of Numeric:


In [2]: import kinds

In [3]: kinds.default_float_kind.M
kinds.default_float_kind.MAX         kinds.default_float_kind.MIN
kinds.default_float_kind.MAX_10_EXP  kinds.default_float_kind.MIN_10_EXP
kinds.default_float_kind.MAX_EXP     kinds.default_float_kind.MIN_EXP

In [3]: kinds.default_float_kind.MIN
Out[3]: 2.2250738585072014e-308

Best,
