The instruction will compare the two source data S1 and S2. The result is stored in three bits
from D.
If a constant K or H used as source data, the value is converted to floating value.

Note: Before the instruction is executed, the comparison data must be all floating numbers (if
it is an integer, it can be converted by FLT instructions); otherwise, the execution result will
be wrong.
