</div>

with the  
[https://processing.org/reference/nf\_.html](https://processing.org/reference/nf_.html)  
can say how many decimals you want show in a string

```auto
println( nf( 0.1234567,0,2) );

```

Not your fault – the reference documentation for nf is actually misleading here.

For further examples and past discussion, also see:

…proposed an update to the reference to help answer this perennial question.

and for the reference page i have 2 more ideas

-a- i like the header menu from the  
[https://p5js.org/reference/](https://p5js.org/reference/)  
so you could just jump directly to the “String Functions” group.

-b- HTML has some more features now,  
how about show some “tool tip” when you are over the link?

 ![html_tooltip_for_processing_refrence](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/2X/7/76ca561d1bbef5164dc6bc86dcd2220dcc207117.png)

because, if you NOT know the command **nf()**

- how can you find it
- why you should click on it.
