Re: [WWdevel] spaces and units in answers

[Michael G. <ga...@ma...>]

I believe the current "parser" uses an initial space to separate the  
units from the number and thereafter there
can be no spaces.  (The regex expression looks for the last non- 
trailing space.)

I'll try to remember to add the no spaces rule to the others on

http://webwork.math.rochester.edu/spring00-phy121/help_units.html

Can't do much more than that for now although I think Davide has  
plans to some day extend the parser
so that it is a true parser of units instead of using regex  
expression matches.

Take care,

Mike
