Added function to convert decimal to binary. To the right of the decimal point are negative powers of 2.
Not sure if this is the method that we will want to use for binary, or if we want to represent individual decimal points as their own 4-bit binary codes.
This function uses a brute force method, and should be optimized using an algorithm later.
Tomorrow, it will be tested to see if it can at least functionally turn decimal into binary. Then further improvements can be made to this function.
