Compute

The *COMPUTE built-in function enables you to define a complex arithmetic expression using the following mathematical operators on a single compute expression line.

For more information on these operations, see, Understanding Built-In Functions *ADD, *SUB, *MULT, *DIV, and *MODULO subtopics earlier in this chapter.

There is one output parameter, the *Result field of the object type FLD, associated with this function type. It contains the result of the computation expression.

Note: You can define several additional parameters as needed by the details of the compute statement.

By default, intermediate results for each operation are contained in *Synon (17,7) Work fields. You can override the work fields with any valid field in the action diagram to contain intermediate results.

Note: The precision of the intermediate result fields affects the overall precision of the *COMPUTE expression. For example, the default fields are defined with a length of 7 decimal digits. Any rounding you specified for a multiplication or division operation occurs only in the following cases:

• The intermediate result has more than 7 decimal digits
• The operation is last in the *COMPUTE expression and the length of the final result field has fewer decimal digits than the calculation requires

To force rounding, ensure that intermediate and final result fields have the appropriate number of decimal digits.
