VALUE
rb_int_lshift(VALUE x, VALUE y)
{
    if (FIXNUM_P(x)) {
        return rb_fix_lshift(x, y);
    }
    else if (RB_BIGNUM_TYPE_P(x)) {
        return rb_big_lshift(x, y);
    }
    return Qnil;
}

Returns self with bits shifted count positions to the left, or to the right if count is negative:

Example

n = 0b11110000
"%08b" % (n << 1)  # => "111100000"
"%08b" % (n << 3)  # => "11110000000"
"%08b" % (n << -1) # => "01111000"
"%08b" % (n << -3) # => "00011110"
