I have following expression

Math.round(effect("Slider Control")("Slider"))

on a text layer to control the text with the slider and be able to make a countdown. How can I make this in "tenner" steps, so when I add two keyframes with "300" and "0", it should countdown, but in "tenner" steps, so 300, 290, 280

1 Answer 1


You divide by 10, round the result, then multiply by 10.

So the formula may be:

Math.ceil(effect("Slider Control")("Slider") / 10) * 10

You may prefer to substitute Math.ceil() with Math.floor() or Math.round() for different timings.
