NJ-series Instructions Reference Manual (W502)
These instructions compare the values of the elements with the same element numbers in two arrays
(In1[0] to In1[Size−1] and In2[0] and In2[Size−1]). The comparison results are stored in comparison
results array AryOut[] in the elements with the corresponding element numbers (AryOut[0] to Ary-
Out[Size −1]).
The value of AryOut[i] is as follows for each instruction:
The following example shows the AryCmpEQ instruction when Size is UINT#3.
• Use the same data type for In1[] and In2[].
• Use an AryOut[] array that is at least as large as the value of Size.
• If In1[] and In2[] contain real numbers, error may cause unexpected processing results. This can
occur, for example, when they contain non-terminating decimal numbers.
• If the value of Size is 0, the value of Out will be TRUE and AryOut[] will not change.
• Return value Out is not used when the instruction is used in ST.
• An error occurs in the following cases. ENO will be FALSE, and AryOut[] will not change.
• If In1[] and In2[] contain different data types.
• If the In1[], In2[], or AryOut[] array is smaller than the value of Size.
Function
Instruction Value of AryOut[i]
AryCmpEQ If In1[i] = In2[i], the result is TRUE. Otherwise, it is FALSE.
AryCmpNE If In1[i] ≠ In2[i], the result is TRUE. Otherwise, it is FALSE.
