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