conversions.decimal_to_binary.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):
