Operation Table:
MOTOROLA
1. If either operand is a NAN, refer to 1.6.5 Not-A-Numbers for more information.
2. Returns + 0.0 in rounding modes RN, RZ, and RP; returns – 0.0 in RM.
3. Sets the OPERR bit in the floating-point status register exception byte.
that number to the number contained in the destination floating-point data register.
Stores the result in the destination floating-point data register.
FADD will round the result to the precision selected in the floating-point control register.
FSADD and FDADD will round the result to single or double-precision, respectively,
regardless of the rounding precision selected in the floating-point control register.
