The double precision floating point is supported by library functions. As such it should give the same results but will be slow.

Single precision FP can be supported by custom instructions - they will be less slow than using the library functions.

good morning,

thanks for the answer.

First what's the solution that can i follow to make my program fast if i will use double precision.

Second, are there any techniques to maintain the same precision and make it fast.

i heared about fixed point we multiply the real number by 2^p and work like using the int type.

thanks an advance
