ECMP Compares the single-precision real number data specified by (s1) with the single-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.

EDCMP Compares 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.

EZCP Compares the band between the single-precision real number specified by lower limit value (s1)
and the single-precision real number specified by upper limit value (s2) with the single-precision
real number in the device specified by comparison data (s3). According to the comparison result
(below, within zone, or above), (d), (d)+1, or (d)+2 is turned on.

Instruction symbol Processing details Reference
EDZCP Compares the band between the double-precision real number specified by lower limit value (s1)
and the double-precision real number specified by upper limit value (s2) with the double-precision
real number in the device specified by comparison data (s3). According to the comparison result
(below, within zone, or above), (d), (d)+1, or (d)+2 is turned on.
