1) Replace the semantics of 6.8.22 IMSQRT with:

If N = 0+0i, then IMSQRT(N)=0. Otherwise IMSQRT(N) is SQRT(IMABS(N)) * sin(IMARGUMENT(N)/2) + SQRT(IMABS(N)) * cos(IMARGUMENT(N)/2) i.

2) Note that the reporter refers to IMLOG which does not exist. I suspect that she meant IMLN:
Replace the semantics of 6.8.13 IMLN with:

IMLN(X) is LN(IMABS(X)) + IMARGUMENT(X)i

X ≠ 0

3) replace the semantics of 6.8.14 IMLOG10 with

IMLOG10(X) is IMDIV(IMLN(X),COMPLEX(LN(10),0))

X ≠ 0

4) replace the semantics of 6.8.15 IMLOG2 with

IMLOG2(X) is IMDIV(IMLN(X),COMPLEX(LN(2),0))

X ≠ 0
