Thread: DECtoBIN Conversion WITHOUT using String Methods

Hey I am trying to create a programme that determines the binary sequence of an input (unknown) decimal number. I DO NOT want to use a String Method.

I am running into the difficulty that my remainder is stuck on an endless loop. I want to find the divisible value of the decimal number (ie the quotient) and it's remainder, then print the remainder. Then continue calculating the divisible value of the quotient and its subsequent remainder until the quotient is 0.

For example the decimal number 10 should produce a binary sequence 1010.

The code I have written is shown below.

Can anyone please advise?



//Prompt user to input decimal value
System.out.print("please enter the decimal value: ");
decimal = keyboardIn.nextInt();



do
{
//Calculations
quotient = decimal/2;//
remainder = decimal%2;
System.out.print(" " +remainder);
quotient = decimal;
counter++;
}while (quotient !=0);

Hey Norm,

The variable that the binary sequence is held in is an int variable. I have included the full code below.

The quotient would ==0 as shown in the following example:

decimal = 10

quotient = decimal/2;
remainder = decimal%2;

therefore,
quotient = 10/2 = 5
remainder = 10%2 = 0

quotient = 5/2 = 2
remainder = 5%2 = 1

quotient = 2/2 = 1
remainder = 2%2 = 0

quotient = 1/2 = 0 // quotient ==0
remainder = 1%2 = 1

<code>
public class DecToBin
{
public static void main(String[]args)
{
Scanner keyboardIn = new Scanner (System.in);

<var>
// declare variables
int decimal, quotient, remainder, counter =1;


//Prompt user to input decimal value
System.out.print("please enter the decimal value: ");
decimal = keyboardIn.nextInt();



do
{
quotient = decimal/2;
remainder = decimal%2;
System.out.print(" " +remainder);
quotient = decimal;
counter++;


}while (quotient!=0);




}//end main method
}//end class
