Real.value(String) can return success but fail to encode some large negative values

[BillHurn]

A test put in to check the handling of values that are unencodable as Real spotted some odd results around Long.MIN_VALUE

Despite returning a success code, the encoding can fail, resulting in an incorrect value.
