[Python-ideas] Python Float Update

[Joonas Liik]

Having some sort of decimal literal would have some advantages of its own,
for one it could help against this sillyness:

>>> Decimal(1.3)
Decimal('1.3000000000000000444089209850062616169452667236328125')

>>> Decimal('1.3')
Decimal('1.3')

I'm not saying that the actual data type needs to be a decimal (
might well be a float but say shove the string repr next to it so it can be
accessed when needed)

..but this is one really common pitfall for new users, i know its easy to
fix the code above,
but this behavior is very unintuitive.. you essentially get a really
expensive float when you do the obvious thing.

Not sure if this is worth the effort but it would help smooth some corners
potentially..
