Hello Sushil,

FP maths can be done on any platform and microprocessors don't "require" an FPU, they just use one to speed things up.

In most applications it will not make sense to use FP, if only because of the performance penalty (according to the manual of my Raisonance compiler it takes 20 cycles to add or subtract two 32 bit integers and 220 cycles to do the same with two FP numbers). However, if you do need FP, there is not reason why you couldn't. The Raisonance 'math.h' library includes sin, cos, tan, sqrt, etc.
