Does anyone know of a simple, BSD (or compatible) licensed software math library that emulates floating point numbers? Ideally, it should be a single .c file library that implements basic operations (+, -, *, /, negation, comparisons, convert to/from machine integers and strings), that uses a standard C type (int or long long) to store the value, and is usable in the kernel. Alternatively, how about a fixed-point library with the same properties? (I know it's easy to do, but don't want to reinvent the wheel again if I don't have to). Please disregard my earlier message on this subject, if you received it.
