include

include(value) -> Boolean

Determines whether the value is included in the range.

This assumes the values in the range have a valid strict weak ordering (have valid semantics for the < operator). While ObjectRange mixes in Enumerable, this method overrides the default version of include, and is way more efficient (it uses a maximum of two comparisons).

Examples


$R(1, 10).include(5)
// -> true

$R('a', 'h').include('x')
// -> false

$R(1, 10).include(10)
// -> true

$R(1, 10, true).include(10)
// -> false
