Argmin
ordering-functions argmin
syntax
- argmin(a, b, .. , n)
definition
argmin(a, b, .. , n) results in a uint32 data-item with the order number of the argument with the lowest value for the element-by-element comparison.
The domain-unit of the resulting item is the same as the domain units of all arguments of the function.
The values-unit of the resulting item is value-type of the domain unit of of all arguments of the function.
If the lowest value occurs more than once, the function results the first order number.
null is considered higher than any other value.
applies to
Data items with Numeric or string value type
conditions
- Domain of the arguments must match or be void.
- Arguments must have matching:
example
attribute<uint32> argminABC (DomDomain) := argmin(A, B, C);
| A(int32), sequencenr: 0 | B(int32), sequencenr: 1 | C(int32), sequencenr: 2 | argminABC |
|---|---|---|---|
| 0 | 1 | 2 | 0 |
| 1 | -1 | 4 | 1 |
| -2 | 2 | 2 | 0 |
| 4 | 0 | 7 | 1 |
| 999 | 111 | -5 | 2 |
| 2 | null | 1 | 2 |
| 0 | 1 | null | 0 |
| null | 1 | 2 | 1 |
| null | null | null | 0 |
| 1 | 1 | 1 | 0 |
DomDomain, nr of rows = 10
In earlier versions (before 7.202) a null value in one of the arguments could result in a null value of the resulting data item
