Handling Of Numerical Value - Mitsubishi Electric 700 Series Programming Manual

3.21 Handling of Numerical Value

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