Pow
arithmetic-functions power (^)
syntax
- pow(base, exp)
- base^exp
definition
pow(base, exp) or base^exp results in the element-by-element exponentiation of the base values of data-item base to the corresponding exponent values of data item exp.
description
The power operator can not (yet) be used associative, expressions as: a^b^c are not allowed, use (a^b)^c instead.
applies to
Data items with float32 or float 64 value-type
conditions
- Domain of the arguments must match or be void (literals or parameters can be calculated with data items of any domain).
- Arguments must have matching:
example
1. attribute<float32> powAB (ADomain) := pow(A, B);
2. attribute<float32> powAB (ADomain) := A^B;
| A | B | powAB |
|---|---|---|
| 0 | 1 | 0 |
| 1 | 1 | 1 |
| 4 | 2 | 16 |
| 7 | 3 | 343 |
| -5 | -2 | 0.04 |
