Module Contents

.. py:function:: decimal_to_binary_iterative(num: int) -> str

   Convert an Integer Decimal Number to a Binary Number as str.
   >>> decimal_to_binary_iterative(0)
   '0b0'
   >>> decimal_to_binary_iterative(2)
   '0b10'
   >>> decimal_to_binary_iterative(7)
   '0b111'
   >>> decimal_to_binary_iterative(35)
   '0b100011'
   >>> # negatives work too
   >>> decimal_to_binary_iterative(-2)
   '-0b10'
   >>> # other floats will error
   >>> decimal_to_binary_iterative(16.16) # doctest: +ELLIPSIS
   Traceback (most recent call last):
       ...
   TypeError: 'float' object cannot be interpreted as an integer
   >>> # strings will error as well
   >>> decimal_to_binary_iterative('0xfffff') # doctest: +ELLIPSIS
   Traceback (most recent call last):
       ...
   TypeError: 'str' object cannot be interpreted as an integer


.. py:function:: decimal_to_binary_recursive(number: str) -> str

   Take an integer value and raise ValueError for wrong inputs,
   call the function above and return the output with prefix "0b" & "-0b"
   for positive and negative integers respectively.
   >>> decimal_to_binary_recursive(0)
   '0b0'
   >>> decimal_to_binary_recursive(40)
   '0b101000'
   >>> decimal_to_binary_recursive(-40)
   '-0b101000'
   >>> decimal_to_binary_recursive(40.8)
   Traceback (most recent call last):
       ...
   ValueError: Input value is not an integer
   >>> decimal_to_binary_recursive("forty")
   Traceback (most recent call last):
       ...
   ValueError: Input value is not an integer


.. py:function:: decimal_to_binary_recursive_helper(decimal: int) -> str

   Take a positive integer value and return its binary equivalent.
   >>> decimal_to_binary_recursive_helper(1000)
   '1111101000'
   >>> decimal_to_binary_recursive_helper("72")
   '1001000'
   >>> decimal_to_binary_recursive_helper("number")
   Traceback (most recent call last):
       ...
   ValueError: invalid literal for int() with base 10: 'number'
