Fixed/Block-Floating Point Support ...

[Satpreet]

I'm looking to simulate the behavior of a digital hardware arithmetic
block in a C/C++ program.

I was just wondering if there are any libraries (with datatypes and
overloaded operators etc.) available for arithmetic operations on
(variable lenght) Fixed/Block-Floating Point variables ??

Alternatively could anyone throw me a pointer to sample code if
available on the net...
