fAbs

W = (W >= 0) ? W : -W


Find the absolute value of a floating point number.

Forces W to be positive. It works on all numbers including infinity. NaN is unaffected.

The R-Register is not affected.

Dialect restriction: The fAbs instruction is not implemented in boards with dialect numbers less than 6, or which do not have the floating point processor.
