I have a error it looks like you are mixing active and static modes can you help me

My code:

String input = "";

float input1 = 0;
float input2 = 0;
float result = 0;

int operator = 0;

boolean drawResult = false;

void setup() {

  background(255);

  fill(95, 158, 160);

  rect(0, height/5, width, height*4/5);

  textSize(height/10);
  frameRate(90);
  fill(255);
  text("1", 30, height/5*1.7);
  text("2", 30+175, height/5*1.7);
  text("3", 30+175+175, height/5*1.7);

The reason your code isn’t running is because some code isn’t contained within a function, such as draw();

If you delete the last two lines:

println(input);
}

or move the println() statement into draw then the code works fine

Thank you can you make for me because my divided symbol is not work i work until six hour for it i am beginner it my fors project

Also a lot of your visuals are still contained in the setup function, which will only draw once. I would move pretty much everything in setup() to draw() (except the size(), textSize() and frameRate() function)

If you can write it i will very happy i have to make until morning

I know but divided button is not work i tried for example 9/3 it show infinity answer of this problem

It looks like there’s no code that is setting input2 equal to any number, so the denominator will always be zero (hence infinity)

I hope you can help me i have to finish until this morning.

Oh ok. Well I was wrong about the input2 thing because I noticed you actually do have code for this. I would print input2 after parsing the ordinary input text and test different numbers. If the result is always 0 then it may be a problem with parsing

println("=");
    input2 = parseInt(input.substring(1)); //.substring(1) removes 1 symbol from the text
    println(input2);
    input = input + "=";

If this is the case then try adding a radix to your parseInt()

input2 = parseInt(input.substring(1), 10); //.substring(1) removes 1 symbol from the text

Oh. It’s actually a problem I’ve introduced into their code by helping them in another thread by adding .substring(1) to the code above, so that input2 can be +3 or -3 or x3 or /3 and each would be parsed as 3, yet I didn’t notice that they don’t actually add the / symbol, so it gets sent as 3, goes through .substring(1) that removes the first and only character, turns into nothingness, which is then parsed as 0.

Solution?

Make your code for / (divide) set input as /, exactly the same way other + - x functions do it.

Try figuring that out yourself! You gotta start somewhere doing that and not have other people write it for you, isn’t that right? :smiley:
