Cube Root of Negative Numbers: ERROR

*The Cube Root of Negative Numbers returns an ERROR*

It seems that gnumeric cannot calculate the cube root of negative numbers. I have tested a couple of programs and found these results:

=POWER(-27, 1/3) returns
 #VALUE! in OOo 2.1
 #NUM! in gnumeric 1.7.6
 "-3" in MS Excel XP => TRUE

R returns an ERROR, too: (-27)^(1/3) returns "NaN".

Seems, a lot of software gets it wrong, though Excel manages to calculate it.
I hope therefore, that this gets corrected in gnumeric, too. Should I post it as a BUG?

Kind reagrds,

Leonard Mada
