Re: [Mathlib-develop] decimal point versus decimal comma

[Stefan M. <st...@he...>]

Dear BB,
the mentioned bug regarding "," and "." has been fixed over christmas.

It has to do with the Locale set in JMathLib. For the output of numbers
I have set the local to english. Hope this solves all issues.

Regards,
  Stefan.
