is not really an "accuracy" but a level. What is the range of numbers you expect, and how many 'decimal points' of "accuracy"? It might be that your arithmetic range fits in a 16 bit integer in which case you could get a lot of bang/buck out of fixed point numbers. MS Robert Szewczyk wrote:
Floating point support is available, but it is not fast. GCC has supported floating point ops for both avr and MSP430; fancy floating point functions (trig, exp, log, etc.) are available through libm.

None of them have hardware for floating point, however does the compiler (or libraries) provide support for it. I was modifying my code (which probably would be used on micaz or tmote) and was wondering if code like this would give expected results. float mfactor = 0.75; rate = rate *mfactor; I am looking for accuracy upto 10^-4 or 10^-5 Thanks Sumit -- We act as though comfort and luxury were the chief requirements of life, when all that we need to make us happy is something to be enthusiastic about.
