Hello.
In the description of the POW() function it says:
...For a negative base of type int or float and a non-integral exponent, a complex result is obtained. For example, pow(-9, 0.5) returns a value close to 3j.
I guess I would have to say "a non-integer exponent" instead of "a non-integral exponent"
Also in the Spanish version it says "no integral"
Thank you and sorry if I'm wrong
