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 associatively, expressions such as a^b^c are not allowed, use (a^b)^c instead.

applies to

Data items with float32 or float64 value type

conditions

1. Domain of the arguments must match or be void (literals or parameters can be calculated with data items of any domain).
2. Arguments must have matching:
   • value type

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
