It just depends if you want to keep Decimal accuracy, floating point
numbers lose some accuracy, it's up to you. Technically speaking
floats are a little faster.

It's in the standard library,
from decimal import Decimal
# Note that it takes a string
a = Decimal('3.14')
print a
3.14
b = 3.14
type(b)
<type 'float'>
# Note that you cast it to a string first
c = Decimal(str(b))
print c
3.14
a == c
True
