Operation description
Out of the values stored in LDR100, LDR110, LDR120, LDR130, and LDR140, stores the maximum value in LDR200.
Up to 15 arguments can be used.
Script
Operation description
Out of the values stored in LDR100, LDR110, LDR120, LDR130, and LDR140, stores the minimum value in LDR200.
Up to 15 arguments can be used.
Script
Operation description
Calculates the exponential function of the value of D20 and the result is stored in D10.
Only the data type Float32(F) can be used.
Script
Operation description
Calculates the natural logarithm of the value of D20 and the result is stored in D10.
Only the data type Float32(F) can be used.
Script
Operation description
Calculates the logarithm of the value of D20 with 10 as the base and the result is stored in D10.
Only the data type Float32(F) can be used.
Script
Operation description
Calculates the power of a value.
For example, when the value of D20 is 10 and the value of D30 is 5, the function calculates 10 to the power of 5 and
stores the result in D10.
Only the data type Float32(F) can be used.
