In developing fixed-point applications, it is convenient to define functions
to handle the :meth:`quantize` step::
- def mul(x, y, fp=TWOPLACES):
- return (x * y).quantize(fp)
- def div(x, y, fp=TWOPLACES):
- return (x / y).quantize(fp)
-
+ >>> def mul(x, y, fp=TWOPLACES):
+ ... return (x * y).quantize(fp)
+ >>> def div(x, y, fp=TWOPLACES):
+ ... return (x / y).quantize(fp)
>>> mul(a, b) # Automatically preserve fixed-point
Decimal('325.62')
>>> div(b, a)
