2 Instruction Descriptions
2-90
NJ-series Instructions Reference Manual (W502)
• If the data types of In1 to InN are different, they will be expanded to a data type that includes the
ranges of all of the data types.
• Signed integers (SINT, INT, DINT, and LINT) cannot be compared to unsigned integers (USINT, UINT,
UDINT, and ULINT).
• If In1 to InN2 are real numbers, error may cause unexpected processing results. This can occur, for
example, when they contain non-terminating decimal numbers.
• Two values that are positive infinity or two values that are negative infinity are equivalent.
• If any of the values of In1 to InN is nonnumeric data, the value of Out is FALSE.
• If this instruction is used in a ladder diagram, the value of Out changes to FALSE if an error occurs in
the previous instruction on the rung.
