Slider (Decimal) to Binary

[Andy Benham]

Hello all,

I would like to control a text layer to read a padded 10-bit binary number, ideally controlled by a slider.

ie.
0 Decimal = 0000000000

512 Decimal = 10000000000

1024 Decimal = 1111111111

I can’t find any expressions that would work to do this, although I imagine it should be quite trivial, I can’t imagine nobody has ever needed to do this before?

Suggestions welcome.

Yup, it’s pretty easy. just add this code to the source text of the text layer :

decimal = thisComp.layer("slider controller").effect("Slider Control")("Slider");
Number(decimal).toString(2) 
// done by VFXING

That’s perfect, thank you 🙂

Any suggestions on how to pad to 10 bits?

That would be:

decimal=effect("Slider Control")("Slider").value;
binary = decimal.toString(2).padStart(10,"0");

Thank you so much both – that’s absolutely perfect.

You’re welcome.
