Explanation of function and operation
1. 32-bit operation (DEZCP and DEZCPP)
The comparison values [
+1,
], [
+1,
] are compared with the comparison source
[
+1,
] as floating point data, and either bit among
,
+1, and
+2 turns ON
according to the result (smaller, same or larger).
• When a constant (K or H) is specified as [
+1,
], [
+1,
], or [
+1,
], it is
automatically converted into binary floating point when the instruction is executed.
Cautions
1. Number of occupied devices
Three devices are occupied from
(
,
+1 and
+2).
Make sure that these devices are not used for any other purpose.
2. Comparison values [
+1,
] and [
+1,
]
Make sure that two comparison values have the following relationship:
[(
+1, ]
≤
[
+1,
]
In the case of "[
+1,
]
>
[
+1,
]", the value [
+1,
] is regarded as [
+1,
] value during comparison.
