Handling of Numerical Value

3.21 Handling of numerical value
The built-in PLC function has instructions that handle numerical values indicated in 16-
bit and 32-bit.
The most significant bit of the 16-bit or 32-bit are used to indicate whether the value is
positive or negative. Therefore, the numerical values that can be handled are as
follows.
16-bit: -32768 to 32767
32-bit: -2147483648 to 2147483647
