+Use the modulo operator (`%`) to find values of single and tens digits.
+Find which ordinal pattern digits match.
+If digit is found in teens pattern, use teens ordinal.
+
+```js
+const setDigits = ( int=0, len=1, dir=0 ) => {
+    return dir > 0 ? int.toString().padStart(len, "0") : int.toString().padEnd(len, "0");
+}
+// setDigits(1, 2, 0) -> "10"
+// setDigits(1, 2, 1) -> "01"
+// setDigits(11, 2, 1) -> "11"
+```
