The table below contains descriptions associated with the calculator step:
| Function | Description | Required fields |
|---|---|---|
| Set field to constant A | Create a field with a constant value. | A |
| Create a copy of field A | Create a copy of a field with the given field value. | A |
| A + B | A plus B. | A and B |
| A - B | A minus B. | A and B |
| A * B | A multiplied by B. | A and B |
| A / B | A divided by B. | A and B |
| A * A | The square of A. | A |
| SQRT( A ) | The square root of A. | A |
| 100 * A / B | Percentage of A in B. | A and B |
| A - ( A * B / 100 ) | Subtract B% of A. | A and B |
| A + ( A * B / 100 ) | Add B% to A. | A and B |
| A + B *C | Add A and B times C. | A, B and C |
| SQRT( A*A + B*B ) | Calculate ?(A2+B2). | A and B |
| ROUND( A ) | Returns the closest Integer to the argument. The
result is rounded to an Integer by adding 1/2, taking the floor of the
result, and casting the result to type int. In 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 following method ROUND( A, B ) with no decimals (B=0). |
A |
| 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, convergent rounding, statistician‘s rounding, Dutch rounding, Gaussian rounding, odd-even 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". | A and B |
| STDROUND( A ) | Round A to the nearest integer. The used rounding method is "Round half away from zero", it is also called standard or common rounding. In Germany it is known as "kaufm?nnische Rundung" (and defined in DIN 1333). | A |
| STDROUND( A, B ) | Same rounding method used as in STDROUND (A) but with B decimals. | A and B |
| CEIL( A ) | The ceiling function map a number to the smallest following integer. | A |
| FLOOR( A ) | The floor function map a number to the largest previous integer. | A |
| 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. | A and B |
