Binary Floating Binary Floating
(D11, D10) > (D21<D20)
Binary Floating Binary Floating
(D11, D10) = (D21<D20)
Binary Floating Binary Floating
(D11, D10) < (D21<D20)
Binary Floating Binary Floating
The status of the destination device will be kept even if the ECMP instruction is deactivated.
z The binary float data of S1 is compared to S2. The result is indicated by 3 bit devices
specified with the head address entered as D.
z If a constant K or H used as source data, the value is converted to floating point before
the addition operation.
