Hi, I was wondering if there is a way to split double into its integer part and decimal part.
I' working on binary converter, and my teacher gave me 4 steps on how to write the program.
I've completed step 1 which is separating number into integer and decimal portion, and step 2 which is converting integer portion. However, in step 3 I have to multiply decimal part by 2, and then split it into integer and decimal portion. It was easy in step 1 because the number was a string from a keyboard, but in step 3 the decimal part is double so I can't use the substring or split method for substring. :( Can you guys please help me?
This is my code for up to step 3:
(I'm using ArrayStack and ArrayQueue classes that I wrote).

``````public static void main(String[] args)
{

Scanner keybrd = new Scanner(System.in);
ArrayStack<Integer> intStack = new ArrayStack <Integer>();
ArrayQueue<Double> decQueue = new ArrayQueue<Double>();
do
{

/*
* Step 1 - separating the base 10 number
*/

String number="";
int intPart=0;
double decPart=0;
String decimalPart= "";
String integerPart = "";

System.out.println("Enter a number to be converted:");
number = keybrd.nextLine();

for(int i = 0; i < number.length(); i++)
{
if (number.charAt(i) == '.')
{
while (i < number.length())
{
decimalPart +=number.charAt(i);
i++;
}
decPart = Double.parseDouble(decimalPart);
}
else
{
integerPart +=number.charAt(i);
intPart = Integer.parseInt(integerPart);
}
}

/*
* Step 2 - intPart
*/
do
{
intStack.push(intPart%2);
intPart = intPart/2;
}
while (intPart !=0);

/*
* Step 3 - decPart
*/
Double decPartMult = decPart *2;
