You most likely do *not* want floating-point numbers for currency,
since they rely on the operating system's binary floating point
support which cannot accurately represent decimal fractions.
>>> float("34.45")
34.450000000000003
Use the arbitrary-precision decimal.Decimal type instead.
>>> from decimal import Decimal
>>> Decimal("34.45")
Decimal("34.45")
They support the full range of arithmetic operations, without
cumulative precision errors that floats are prone to.
