I'm afraid that's not correct. Decimal is still subject to

I think you wrote to me personally by accident, instead of to the Tutor list.
Nothing you said seems to be private, so I've taken the liberty of answering

For money, you should probably use the builtin module 'decimal' instead:
http://docs.python.org/library/decimal.html
There's also the third party module 'mpmath' which provides arbitrary precision
floating point arithmetic.

i tried writing a small code to calculate option price using the binomial
tree model. I compared my results with results of the same program in
excel. There seems to be a minor difference due to decimal precision as
excel is using 15 decimal precision and python (both 2.7 and 3.1) using 11.
