Don Lewis 36fb8be630 The result of right shifting a negative signed value is implementation ... defined. On machines without arithmetic shift instructions, zero bits may be shifted in from the left, giving a large positive result instead of the desired divide-by power-of-2. Fix this by operating on the absolute value and compensating for the possible negation later. Reverse the order of the underflow/overflow tests and the exponential decay calculation to avoid the possibility of an erroneous overflow detection if p is a sufficiently small non-negative value. Also check for negative values of prob before doing the exponential decay to avoid another instance of of right shifting a negative value.
