number to base string conversion
Dec 23rd, 2005, 4:36pm  
hey all, I hope everyone is having a great holiday! I want to create a function which converts 10 based numbers to other ones. I am getting an error related with my return inside the function. here is the code I have:

int output;// spits the number for recursive arg.
void setup() {
numberToBaseString(24,5);
}

void draw() {

}

numberToBaseString(int num, int base) {
 if(num < base ) {
    output = num;
   }
   else
   {
   int rem = num%base;
    output = rem;
   int reducedNum = (num - rem) / base;
   int rest = numberToBaseString(reducedNum, base);
   output = rem + output;
// this is wrong I guess because I am adding rem + output
// as integers. I need to add them as strings. Any guides?
   }
 return output;
// println(output);
   
}










here is the error I have.


/tmp/build/Temporary_8858_6605.java:10:2:10:19: Semantic Error: The name of the constructor "numberToBaseString" does not match the name of the class "Temporary_8858_6605". Assuming it is a method with missing return type.

I really welcome any corrections from you math guys. Thanks in advance
ilteris.

Hi ilteris,

take a look into this one, it should work:

void setup() {  
 println(numberToBaseString(24, 5));
}

void draw() {
}

String numberToBaseString(int num, int base) {
 String output = "";

 if(num < base ) {  
   output = String.valueOf(num);
 }
 else
 {
   int rem = num % base;
   num = num / base;

   output = numberToBaseString(num, base) + String.valueOf(rem);
 }
 return output;
}

Library class Integer has static method toString(int i, int radix) that should do what you want.
