Automatic Range?

Ruby
1

Problem is simple:
I want to know if an integer is within the range of x and y. However, I
don’t automatically know which of x & y is the largest.

Ruby accepts ranges like (5…2), although there seems to be no real use
for them.

Anyway, is it possible to automatically create a “valid range”, or is
this kind of solution the best one?

range = x < y ? (x…y) : (y…x)

Best regards,

That’s probably as good as it gets. However, Ranges with #end <
#begin are common as arguments to String#[] such as “abcdefg”[2…-2]
=> “cdef”.

Ah, of course - there it makes sense. Thanks!

[x, y].min … [x,y].max
is an alternative
