Reformulate 6.8.16 IMPOWER to read:

6.8.16 IMPOWER

Summary: Returns the complex number X raised to Yth power.

Syntax: IMPOWER (Complex X; Complex Y) or IMPOWER (COMPLEX X; Number Y)

Returns: Complex

Constraints: X ≠ 0

Semantics: IMPOWER (X,Y) is IMEXP(IMPRODUCT(Y, IMLN(X)))

Note: An evaluator implementing this function shall permit any arbitrary Number Y but may allow any arbitrary Complex Y.

The current OpenFormula has:
IMPOWER( Complex X ; Number n )

Gnumeric has IMPOWER( Complex X ; Complex n )
while OOo has IMPOWER( Complex X ; Integer n )

We need to decide what we want to do.
