    Problem Text
    We feel that the correct result is ERANGE. However; the current
    return value is EDOM. The error return value will be changed to ERANGE
    in the next release.
    Test Output
    /tset/ANSI.os/maths/log/T.log 4
    log(), when called with a zero argument, returns -HUGE_VAL and may set
    errno to ERANGE. (In XPG3 mode, log() either returns -HUGE_VAL and
    sets errno to EDOM or ERANGE, or returns NaN and may set errno to EDOM
    or ERANGE.)
    ERRNO VALUES: expected: 34 (ERANGE), observed: 33 (EDOM)
    .sp
    /tset/ANSI.os/maths/log10/T.log10 4
    log10(), when called with a zero argument, returns -HUGE_VAL and may
    set errno to ERANGE. (In XPG3 mode, log10() either returns -HUGE_VAL
    and sets errno to EDOM or ERANGE, or returns NaN and may set errno to
    EDOM or ERANGE.)
    ERRNO VALUES: expected: 34 (ERANGE), observed: 33 (EDOM)

    Status Complete
    Review Recommendation No Resolution Given
    Review Response
    The error indication EDOM was allowed in XPG3 and this system still provides
    this error indication in preference to the XSH4 required error indication of
    ERANGE (which is an alternative in XPG3).

    It is unlikely that this minor difference will affect many applications and it
    is recommended that this minor system fault is accepted.
