Hi everyone. I want to show a float number in a text, but it show like 4 significant numbers.

```auto
float number = 1;
void setup()
{
  background(0);
  size(100,100);
}
void draw()
{
  fill(255);
  text(number,50,50);
  delay(500);
}

```

it show 4 zeros. but i want only 2 or 3 or what i want. How can i code that?

Sounds like you’re looking for the `nf()` function?

Hello,

The Processing page has a list of references:  
[https://processing.org/reference/](https://processing.org/reference/)

The Processing PDE (IDE) also has a list of references; check out the tabs on top to find these.

Check out the ones in the Data \> String Functions sections and choose wisely.
