initialize(argc, argv, obj)

Range.new( start, end, exclusive=false ) -> aRange

Constructs a range using the given start and end. If the third parameter is omitted or is false, the range will include the end object; otherwise, it will be excluded.

==(p1)

===(range, obj)

rng === anObject -> true or false

Returns true if anObject is an element of rng, false otherwise. Conveniently, === is the comparison operator used by case statements.

      case 79
      when 1..50   then   print "low\n"
      when 51..75  then   print "medium\n"
      when 76..100 then   print "high\n"
      end
 produces:
      high

hash()

each()

first(obj)

rng.begin/rng.first -> anObject

exclude_end?(range)

rng.exclude_end? -> true or false

Returns true if rng excludes its end value.

length(range)

rng.length/rng.size -> anInteger
