instance method

Range#eql?

eql?(other) → true or false

static VALUE
range_eql(VALUE range, VALUE obj)
{
    if (range == obj)
        return Qtrue;
    if (!rb_obj_is_kind_of(obj, rb_cRange))
        return Qfalse;
    return rb_exec_recursive_paired(recursive_eql, range, obj, obj);
}

Returns true if and only if:

other is a range.
other.begin eql? self.begin.
other.end eql? self.end.
other.exclude_end? == self.exclude_end?.

Otherwise returns false.

Example

r = (1..5)
r.eql?(1..5)                  # => true
r = Range.new(1, 5)
r.eql?('foo')                 # => false
r.eql?(2..5)                  # => false
r.eql?(1..4)                  # => false
r.eql?(1...5)                 # => false
r.eql?(Range.new(1, 5, true)) # => false

Note that even with the same argument, the return values of == and eql? can differ:

Example

(1..2) == (1..2.0)   # => true
(1..2).eql? (1..2.0) # => false
