x | `Byte` | The integer to be checked. | -
-low | `Byte` | The lower bound to check (inclusive). | -
-high | `Byte` | The upper bound to check (inclusive). | -
+low | `Byte` | One end of the range to check (inclusive); | -
+high | `Byte` | The other end of the range to check (inclusive); | -
-**Return:** `yes` if `low <= x and x <= high`, otherwise `no`
+**Return:** `yes` if `a <= x and x <= b` or `b <= x and x <= a`, otherwise `no`
**Example:**
```tomo

+assert Byte(7).is_between(10, 1) == yes
assert Byte(7).is_between(100, 200) == no
