VHDL type reference for arithmatic

[altersun]

I'm trying to implement an arithmatic-heavy algorithm in VHDL, I already know it works in floating point environments like C. Still, for all the multiplication and division I have to do, I wanted to know what data type would be best, since I have to deal with both positive and negative numbers. Does anyone know a good reference online where there is a lot of info on each VHDL data type? If you're interested in knowing more about the algorithm in question, please ask. Thanks.

If you can get your hands on a floating point library, that is your best bet, as your code will be closer to the C code you ahve written. You can port from C to matlab, then the conversion from matlab to VHDL is easier then most other things.
