Mobile Cart view

Hi

I have added your plugin and almost everything works wonderful. I used your plugin for shop which sells fabrics by meter (actually by 0,1m step and minimal amount 0,5m)

I added product quantity step to 0,1 and minimal quantity to 0,5 in plugin options.

In desktop view everything works wonderful, but in mobile view in cart if I decide to add more length to product that is in cart – the item amount breaks and adds 18 digits behind the comma. First digit after the comma increases by 1 (as intended),but after that comes 16 zeros and ifnal digit (18th) increases also by one digit (similar to first digit after the comma).
Is there an option, where I can limit the amount of digits after the comma, so that I can avoid this kind of problem?

Wanted to mention again, that everything else works wonderful. Thank you for great work and hope you can help me with this problem as well.

Best
