Money data type

[Batista, Facundo]

Can't find it.

I mean something like:
5.35

5.35! Not 5.3500000000000001 neither 5.34999999999999999999.

I think this is not a rare thing, but I can't find it in the standar library
neither the package index.

Thanks!

look at http://fixedpoint.sourceforge.net/ it gives you numeric object
for monetary applications (I have never used it)

If it's merely a matter of representing itself you could do something
blindingly simple like:

class Dollars (float) :

def __repr__ (self) :
return "$%.2f" % self

def __add__ (self, other) :
return Dollars(float.__add__(self, other))

#and so on for the other mathematical operators ...


Note this is _not_ to your spec (ie output includes a currency symbol
and input is simply a float).

def __repr__ (self) :
return "$%.2f" % self

Umm ...you might want to do the same to __str__ if you want to print ... :/
