I need to print a float variable with 2 decimals. I couldn’t find on processing reference
can say how many decimals you want show in a string
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
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?
because, if you NOT know the command nf()
- how can you find it
- why you should click on it.
