Public bug reported:
Binary package hint: gcalctool
Apparently gcalctool computes fractional powers by way of logarithms.
Unfortunately this fails if the base is 0 (the result should always be
1, unless the exponent is 0, in which case it may be undefined, though
gcalctool says 0^0=1). For example 0^(2/3) = 1, but gcalctool complains
"Logarithm of zero is undefined" (which is correct in the reals, since
in y = b^x, for any fixed b != 0 the limit of x as y approaches 0 is
negative infinity). Perhaps this should be a special case.
** Affects: gcalctool (Ubuntu)
Importance: Undecided
