As far as I know there's no way to change the decimal separator, CMUD uses the American format. Why you're getting that error when you try 2.1, I have no idea. What are you trying to do with that expression (store it in a variable, send it to a command/function, etc.)?

No script.
This is result when i just doing in command line:
#show (2+2)
#show (2.1+2)
#show (2,1+2) etc. |

My local decimal separator is , (Poland, win7)
#sh (2+2) -> 4 working
#sh (2.1+2) -> 4.1 working
#sh (2,2+2) -> illegal character in expression: ,
Everything is right. I see no dependency on system settings. |

I suspect the problem is the local Windows settings, but I'm not sure. Cmud does not have any internal method of changing the decimals to use a comma, so it may be an interaction between Windows and Cmud.

CMud does not offer any sort of control over how parameters in a function call are delimited, so effectively CMud in your case cannot tell if (2,1+2) is a list of 2 parameters being passed to some function or the polish locale equivalent of 2.1+2. I don't think it's a matter of knowing/not knowing that the comma is your decimal separator, so much that in your case the decimal separator is now the same as the parameter delimiter (ie, a conflict of functionality).
Since CMud merely inherits the locale settings and doesn't let you override them (and since Windows doesn't let you customize it for individual applications to deal with stuff like this), you will have to execute your math in a different language with better locale support and then convert the results as desired. |

One way of dealing with simple cases like this would be to use division instead of decimals, e.g.:
| Code: |
| #show ((%float(21)/10 + 2) |
But that will be a pain for more complicated cases. |
