Comparable#between?

obj.between?(min, max) → true or false

static VALUE
cmp_between(VALUE x, VALUE min, VALUE max)
{
    if (cmpint(x, min) < 0) return Qfalse;
    if (cmpint(x, max) > 0) return Qfalse;
    return Qtrue;
}

Returns false if obj <=> min is less than zero or if obj <=> max is greater than zero, true otherwise.

Example

3.between?(1, 5)               #=> true
6.between?(1, 5)               #=> false
'cat'.between?('ant', 'dog')   #=> true
'gnu'.between?('ant', 'dog')   #=> false
