  3. If both px and py are Strings, then
    ...
  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).
    d. Assert: Type(nx) is BigInt and Type(ny) is Number, or if Type(nx) is Number and Type(ny) is BigInt.
    e. If x or y are any of NaN, return undefined.
    f. If x is -∞, or y is +∞, return true.
    g. If x is +∞, or y is -∞, return false.
    h. If the mathematical value of nx is less than the mathematical value of ny, return true, otherwise return false.
