Program: Decimal to Binary converter.

THis program accepts fractional values, the accuracy can be set below:
'''
decimal_accuracy = 7

                            # Reasoning for list instead of integer: to avoid integer overflow error.

    whole= []                                   # The part before decimal point
    fractional = ['.']                          # The part after decimal point

    decimal = round(num%1, decimal_accuracy)    # Extract fractional number part of decimal
    w_num = int(num)                            # Extract whole number part of decimal.

    i=0     # Some fractional decimal numbers have infinite binary values, so we limit this loop below.

    #Loop to find binary of decimal part

            if(decimal == 0): break # Removes trailing zeros.
            i = i + 1
