Hmm I see. Then do I have to extend the lexer like following?
http://www.antlr.org/wiki/display/ANTLR3/Lexer+grammar+for+floating+point,+dot,+range,+time+specs Cause it seems like very complicated for what I want to achieve... In my language FLOAT does not have a conflict with the range because I do not allow a float number such as .123 (dot has to be preceded by number like 0.123) Is there easier way which uses the fact that I'm now allowing .123 style floating point number? Thanks.
