in reply to How to check if a variable's value is equal to a member of a list of values

If your values are members of ranges, you could go through the list once at startup and remember just the start/ends of the ranges, then compare to those. For example, if your list is like:

1, 2, 3, 4, 5, 453, 454, 455, 456, 457, 458

You'd remember only 1 - 5 and 453 - 458, then check if x is within any stored ranges.




Time flies like an arrow. Fruit flies like a banana.
