Outputting a comparison result of double-precision real numbers
EDCMP(P)
These instructions compare the double-precision real number data specified by (s1) with the double-precision real number
data specified by (s2), and according to the result (small, equal, or large), (d), (d)+1, or (d)+2 is turned on.
