Decimal numbers in expression

Question

Hi! I have created a counter on a text layer that counts length in increments om 40 cm controlled by a slider, I added this expression to the source text property and it works great except for the decimals.

t = effect("Slider Control")("Slider")

x = Math.round(t/.4)*.4+0.0001

x = x + " Meter"

x.toString().replace(".", ",");

It now counts 0,001 Meter.... 0,4001 Meter... 0,8001 Meter.... 1,2001 Meter..... but i want it to only show 2 decimals: 0,40..0,80..1,20..1,60...

I added the +0.0001 in Math.round to get decimals at the whole numbers. I.e. 4 Meter is now 4,0001 Meter... But how do I remove the last two digits? Or is there another way to always show 2 decimals? I need the counter speed to be controlled over time and masking is a problem since the font I use is not monospaced.

Thank you.

Sorry, I completely missed the increments of 0.40 part. That would change it to:

t = effect("Slider Control")("Slider").value;

x = (Math.round(t/.4)*.4).toFixed(2) + " Meter";

x.toString().replace(".", ",");

Solution:I added another "replace string" at the bottom and removed the last "01" in the decimals with empty space. I then created a second text layer and pick whipped the source text to layer 1 source text. full expression, Layer 1 :t = effect("Slider Control")("Slider")x = Math.round(t/.4)*.4+0.0001x = x + " Meter"x.toString().replace("01", "");In Layer 2 i added the:.toString().replace(".", ",");string and made this the actual visible counter.Full expression, Layer 2.thisComp.layer("Layer1").text.sourceText.toString().replace(".", ",");
