【ABS】Input by absolute value, ex: value 0.500, input-0.1, and it will show -0.100.
【INC】Input by increase value, ex: value 0.500, input-0.1, and it will show 0.400.
【NORUNT】Input by normal unit,ex: value 0.500, input 1, and it will show 1.000.
【MINUNT】Input by minimum unit,ex: value 0.500, input 1, and it will show 0.001.
Each column as below：
Type：Tool type
