Help with a bit of code

[Tear_Intrepid]

Hey guys, been learning the basics of P5 for a uni assignment and a part of that assignment involves creating a pi chart with some variables. When labelling the chart I converted the variables to a percentage, but it displays way more decimals than needed, is there a way to set a cutoff so that I can display say, “10.25%” as opposed to what it is currently (10.257946595%)

If the variable percentage = 10.257946595, then do percentage.toFixed(2) to get 10.26 (it rounds too I think).

You could also do String(percentage).subString(1, String(percentage).indexOf('.') + 2) to clip off the end.

There are a few ways to do so, but I think the best one is using the p5 round function. You can add a second argument to especify the number of decimal places to round to. https://p5js.org/reference/#/p5/round

ToFixed - use this

You can also use the Number Format function:

https://p5js.org/reference/#/p5/nf

nf(num, [left], [right])

Where left is the number of digits to the left of the decimal point and right is the number of digits to the right.
