    Problem Text
    This was withdrawn because it is a duplicate. Use req.4.U.00203
    instead.

    We believe this is a test suite deficiency. Our implementation
    supports only roud-to-nearest rule, and is rounding correctly.
    For a negative number (such as -12345.987500), we are producing
    the correct results per the round-to-nearest rule.

    The round-to-nearest rule for a negative number algorithm is to:
    1. take absolute value of number,
    2. round next-to-last digit _up_ if last digit it 5-9
    3. apply sign of original number to result

    Or logically:

    if (number < 0)
    if (last digit == 0-4)
    (leave next digit as is)
    else
    (round next digit _down_)
    else
    if (last digit == 0-4)
    (leave next digit as is)
    else
    (round next digit _up_)
