My C docs say a negative number produces a domain error. A
zero produces a range error. Assuming these Open Watcom
docs are correct, I've specified the argument must be a
positive NUMBER or FLOAT, hence my notation (0,inf] - you
correctly assumed my "(" means open and "]" means closed for
ranges. Of course it may be better to always consider "inf"
as open.
Please let me know if you spot any errors or a need for
clarification.
