Module Contents
---------------

.. py:function:: benchmark() -> None

   Benchmark multiple functions, with three different length int values.


.. py:function:: num_digits(n: int) -> int

   Find the number of digits in a number.

   >>> num_digits(12345)
   5
   >>> num_digits(123)
   3
   >>> num_digits(0)
   1
   >>> num_digits(-1)
   1
   >>> num_digits(-123456)
   6
   >>> num_digits('123')  # Raises a TypeError for non-integer input
   Traceback (most recent call last):
       ...
   TypeError: Input must be an integer


.. py:function:: num_digits_fast(n: int) -> int

   Find the number of digits in a number.
   abs() is used as logarithm for negative numbers is not defined.

   >>> num_digits_fast(12345)
   5
   >>> num_digits_fast(123)
   3
   >>> num_digits_fast(0)
   1
   >>> num_digits_fast(-1)
   1
   >>> num_digits_fast(-123456)
   6
   >>> num_digits('123')  # Raises a TypeError for non-integer input
   Traceback (most recent call last):
       ...
   TypeError: Input must be an integer


.. py:function:: num_digits_faster(n: int) -> int

   Find the number of digits in a number.
   abs() is used for negative numbers

   >>> num_digits_faster(12345)
   5
   >>> num_digits_faster(123)
   3
   >>> num_digits_faster(0)
   1
   >>> num_digits_faster(-1)
   1
   >>> num_digits_faster(-123456)
   6
   >>> num_digits('123')  # Raises a TypeError for non-integer input
   Traceback (most recent call last):
       ...
   TypeError: Input must be an integer
