FRCPA.S – Floating Point Reciprocal Approximation
Description
Returns an approximation of the reciprocal of the operand. This can be used as a starting point
for iterative approximation algorithms. Also checks the operand for the special values Infinity,
Not-a-Number and Denormal. A check is also performed for values with the two biggest possible
representable exponents, i.e. 0xFD and 0xFE. This is useful for avoiding overflow in intermedi-
ate calculations in certain iterative algorithms. The operation sets the status flags according to
the result of this check.
