(Convert from Floating Point to fixed point (integer))
Converts the number in floating point register W to an integer nn, Pushes the integer result to X and sets a Return Code in R.
The resulting number in X, and the result code in R, depend on the number in W

Note that in the normal range 0 to 255 (and down to -255), the fix instruction truncates the argument. Thus 13.999 (and -13.999) gives the result 13.
Dialect restriction: The fix instruction is not implemented in boards with dialect numbers less than 6, or which do not have the FP processor.
