I want to print a Decimal Number in reverse.

Hi :(hi):, I am new to Java, and I am suppose to implement a recursive method that writes the digits of a DECIMAL number in opposite/reverse order. The number is positive so you do not need to worry about negative signs etc.

What I have is below...I know it works for Integer numbers, but I do not think it will work for decimals.. I was helped out earlier, and was told, that the 10 is a "good number" to use for dividing the input number..I am unsure why?:s:

Code:

---

void reverseDigits(int number){
if(number >= 0) // Make sure we have a positive number
{
if(number < 10)
System.out.print(number);
else
{
System.out.print(number % 10);        // This prints the right most number first (or in position 1)
reverseDigits(number / 10);        // The remainder of the digits are to follow
}
}

can`t follow you ...:(think):

Quick question... have you tried it out with a double or a float value to see if it works with decimals?
