FICOM             Integer Compare             Exception Flags: I D

FICOM source

       Logic:      cmp source, ST
                   sets condition codes in the status word:

                   C3 C2 C1 C0    Means
                   -- -- -- --    -----------
                   0  0  ?  0     ST > source
                   0  0  ?  1     ST < source
                   1  0  ?  0     ST = source
                   1  1  ?  1     ST not comparable to source

     FICOM compares two integers and leaves the result encoded in the status
     word as shown above. The source operand can be either a memory short
     integer or a memory word integer, and the implied destination is ST.
