Precautions for Correct Use

The input variables are not allowed to omit. An error will occur during the compiling of the software if
any input variable is omitted. But the output variable is allowed to omit.

The input value of In2 can not be 0. In other words, the divisor in the division operation can not be 0.
The value of Out will be 0 if the value of In2 is 0.

Programming Example

The data types of variables MODABS _In1 and MODABS _In2 are both REAL and the data type of
Out1 is LREAL. The values of MODABS _In1 and MODABS _In2 are 400.23 and 360.0 respectively.
The value of Out1 is 40.2300109863281 when MODABS _EN changes to TRUE. The values of
MODABS _In1 and MODABS _In2 are -400.23 and 360.0 respectively. The value of Out1 is
319.769989013672 when MODABS _EN changes to TRUE.
