change dash formula precision

dashes are not showing evenly spaced in some scenarios. <img width="1920" alt="uneven-dashes" src="https://github.com/user-attachments/assets/e814ace7-3e16-4b3f-b474-29fe87683a54"> This is due to the default precision we use for Wang's formula. ended up changing the precision only for dashes because from my tests, follow path and trim path didn't make a big difference.
