Function
MAX
The MAX instruction finds the largest value of two to five data to process, In1 to InN.
MIN
The MIN instruction finds the smallest value of two to five data to process, In1 to InN.
The following example is for the MAX instruction when In1 is INT#10, In2 is INT#5, In3 is INT#23, In4 is
INT#14, and In5 is INT#−5.

Additional Information
To find the largest or smallest of six or more values, use the AryMax or AryMin instruction (page 2-312).
Precautions for Correct Use
• In1 to InN and Out may be different data types, but observe the following precaution.
• Set the valid range of Out to include the valid ranges of In1 to InN.
• Do not combine signed integers (SINT, INT, DINT, and LINT) together with unsigned integers
(USINT, UINT, UDINT, and ULINT) for In1 to InN.
• If In1 to InN are real numbers, the desired results may not be achieved due to error.
