Note that with a properly crafted regex, the timing difference between it and substr is pretty small; limiting the scope of bigint and using the look-ahead regex from Re^2: Print Number With Implied Decimal Point:

Rate regex substr regex2 regex 2926/s -- -78% -80% substr 13087/s 347% -- -11% regex2 14782/s 405% 13% --
