Attributes:
Description: Converts the source operand to extended precision (if necessary) and
Operation Table:
5-94
multiplies that number by the number in the destination floating-point data register.
Stores the result in the destination floating-point data register.
FMUL will round the result to the precision selected in the floating-point control register.
FSMUL and FDMUL will round the result to single or double precision, respectively,
regardless of the rounding precision selected in the floating-point control register.
NOTES:
1. If the source operand is a NAN, refer to 1.6.5 Not-A-Numbers for more information.
2. Sets the OPERR bit in the floating-point status register exception byte.
