Calculator

Description

Calculator is a step in the Transform Plugin for Process Studio Workflows. The calculator step provides predefined calculation expressions that can be executed on input field values. It can take up to three input arguments (Field A, Field B and Field C) and a return type must be specified. You may perform multiple such calculations within the step that are independent of each other or depend on fields generated in previous calculations. There is an option to remove fields from the output after all values are calculated. This is useful for removing temporary values.

Note: The execution speed of the Calculator is far better than the speed provided by custom scripts (JavaScript).

Calculations Available

The table below contains the available calculations and associated descriptions:

No.	Calculation	Explanation
1	Set field to constant A	Create a field with a constant value.
2	Create a copy of field A	Create a copy of a field with the given field value.
3	A + B	A plus B.
4	A - B	A minus B.
5	A * B	A multiplied by B.
6	A / B	A divided by B.
7	A * A	The square of A.
8	SQRT( A )	The square root of A.
9	100 * A / B	Percentage of A in B.
10	A - ( A * B / 100 )	Subtract B% of A.
11	A + ( A * B / 100 )	Add B% to A.
12	A + B *C	Add A and B times C.
13	SQRT( AA + BB )	Calculate ?(A2+B2)
14	ROUND( A )	Returns the closest Integer to the argument. The result is rounded to an Intege by adding 1/2, taking the floor of the result, and casting the result to type int. I other words, the result is equal to the value of the expression: floor (a + 0.5). In case you need the rounding method "Round half to even", use the followin method ROUND( A, B ) with no decimals (B=0).
15	ROUND( A, B )	Round A to the nearest even number with B decimals. The used rounding method is "Round half to even", it is also called unbiased rounding, convergen rounding, statistician's rounding, Dutch rounding, Gaussian rounding, odd-eve rounding, bankers' rounding or broken rounding, and is widely used in bookkeeping. This is the default rounding mode used in IEEE 754 computing functions and operators. In Germany it is often called "Mathematisches Runden".
16	STDROUND( A )	Round A to the nearest integer. The used rounding method is "Round half awa from zero", it is also called standard or common rounding. In Germany it is known as "kaufmännische Rundung" (and defined in DIN 1333).
17	STDROUND( A, B )	Same rounding method used as in STDROUND (A) but with B decimals.
18	CEIL( A )	The ceiling function maps a number to the smallest following integer.
19	FLOOR( A )	The floor function maps a number to the largest previous integer.
20	NVL( A, B )	If A is not NULL, return A, else B. Note that sometimes your variable won't be null but an empty string.
21	Date A + B days	Add B days to Date field A. Note: Only integer values for B are supported. If you need non-integer calculations, please add a second calculation with hours.

42	Remove time from a date A	Removes time value of A. Note: Daylight Savings Time (DST) changes in Sao Paulo and some other parts of Brazil at midnight 0:00. This makes it impossible to set the time to 0:0 at the specific date, when the DST changes from 0:00 to 1:00 am. So, there i one date in one year in these regions where this function will fail with an "IllegalArgumentException: HOUR_OF_DAY: 0 -> 1".
