FISUBR Integer Subtract Reversed Exception Flags: I D O P
FISUBR memory operand
Logic: ST . memory operand - ST
FISUBR subtracts two integers (memory operand - ST) and leaves the
result in the stack top. The memory operand must be a word or short
integer. The destination implied in the instruction is ST.
This instruction is the reversed form of FISUB, which subtracts memory
operand from ST (ST - memory operand).
