Hi all.
Is there a way I can keep my floating point number as I typed it? For
example, I want 34.52 to be 34.52 and NOT 34.5200000002.
Hi Bradley,
Use the Decimal type instead. It's not as convenient as float, but it
will give you a consistent representation of your numbers.
The behavior of floating point numbers surprises a lot of people and
has been discussed at length a number of times here (and elsewhere).
If you're in the mood for EXTREMELY thorough coverage of the subject,
you can read this:

There's a gentler discussion of it here:
