Processing details
• These instructions compare 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.

(d)
Turns on when [(s1) to (s1)+3] > [(s3) to (s3)+3]
(d)+1
Turns on when [(s1) to (s1)+3] ≤ [(s3) to (s3)+3] ≤ [(s2) to (s2)+3]
(d)+2
Turns on when
Precautions
• Set (s1) to a value less than (s2). If (s1) is set to a value greater than (s2), (s2) is treated as the same value as (s1).
Operation error
Error code Description
(SD0)
The value input to (s1) to (s3) is -0, a subnormal number, NaN (not a number), or .
