+  4. Else,
+    a. Let nx be ? ToNumeric(px). Because px and py are primitive values evaluation order is not important.
+    b. Let ny be ? ToNumeric(py).
+    c. If Type(nx) is Type(ny), return ? Type(nx)::lessThan(nx, ny).

+  BigInt::lessThan (x, y)
+
+    The abstract operation BigInt::lessThan with two arguments x and y of BigInt type returns true if x is less than y and false otherwise.
