How to convert string to int

Hi

it's easy, but I don't the proper funtion which is iseful for that. An example, please

Thanks

int(String s) in Processing or else Integer.parseInt(String s) in Java should do the job. Example:

void setup(){
  int a = int("128");
  a++;
  println(a);
}

P.S. I know that both the functions can be used with any arguments, not just Strings, but I have not mentioned here as you seem to be a beginner.
Note: int(String s) is exactly the same as Integer.parseInt(String s) .

Hi

I guess that a++ wasn't necessary

Thanks.....

Hi

What would it be the opposite, so, int to string? if you don't matter?

Thanks

Hi

Maybe including float to string

Thanks

Please see the conversion section of the reference. It lists all of the functions for converting from one type to another. If you have a specific question about something you don't understand, then please post some example code that shows where you're stuck.

str()

I used that a++ just to show that it works, otherwise my code would be this println(int("128")) which is kind of stupid.
Excellent answer from KevinWorkman, I never knew that even existed.

Hi

I asked because I didn't find such an obvious question, but somehow after searching

float tf1; tf1=hundredths+(seconds*100); tf1=tf1/100; sf1 = Float.toString(tf1); //Total time

In reference I found this

int i = 65; float f = float(i); println(i + " : " + f); // Prints "65 : 65.0"

Both of them works

Thanks
