Re: Complex square root of -1 : zsqrt(-1)

With this correction,
0e 0e -1e 0e z** z. 0  ok,      it is false, it must be Inf (0^(-1))
With Julia and Matlab, we have:
0^(a + i*b) gives:
  -  0 for a >0 and b in R
  -  1 for a =0 and b = 0
  -  inf for a<0 and b = 0
      ( in this case for julia: 0^(-1) gives Inf and O^(-1+0*im) gives
NaN + im NaN)
      ( but Matlab gives the same result Inf)
  -  NaN + i NaN for a<=0 R and b<>0
