5.3.15 Invert Sign (INV)
( 1 ) Operation
The sign of the input data is inverted and the result is stored in the output data.
( 2 ) Format
∗ C and # registers cannot be used.
( 3 ) Programming Example
In the following programming example, the INV instruction inverts the sign of 12,345 in input data A in MW00000
and stores the result in the output data in ML00002.
-1
×
MW00000 (12,345)
→ ML00002 = -12,345
When performing operations with different data types, the result of the operation will depend on the data type of the output reg-
ister.
Refer to 4.4.2 ( 3 ) Precautions When Using Local Registers within a User Function for details.
