A range is an interval of consecutive integers represented by its endpoints. A range is created with .. operator for inclusive range and ... operator for exclusive range.

Methods

clone()

Get a copy of the range.

IO.println((42..69).clone()) #> 42..69

contains(value)

Return true if the range contains value.

IO.println((42..69).contains(55)) #> true
IO.println((42..69).contains(12)) #> false

from

Return the first endpoint of the range.

IO.println((42..69).from) #> 42
IO.println((12..7).from)  #> 12

See also: to

hash

Compute a hash for the range.

IO.println((42..69).hash) #> -1259079512711543054

inclusive

Return true is the range includes to (from is always included).

IO.println((42..69).inclusive)  #> true
IO.println((42...69).inclusive) #> false

iterate(iterator), iterator_value(iterator)

Implement the iterator protocol to iterate over the range.

max

Return the maximum endpoint of the range.

IO.println((42..69).max) #> 69
IO.println((12..7).max)  #> 12

See also: min

min

Return the minimum endpoint of the range.

IO.println((42..69).min) #> 42
IO.println((12..7).min)  #> 7

See also: max

size

Return the number of elements in the range.

IO.println((42..69).size)   #> 28
IO.println((42...69).size)  #> 27

to

Return the second endpoint of the range. If the range is inclusive, this value is included, otherwise, it is excluded.

IO.println((42..69).to) #> 69
IO.println((12..7).to)  #> 7

See also: from

to_s

Transform the range to a String.

IO.println(42..69) #> 42..69
IO.println(42...69) #> 42...69
