I prefer to get 6.0 Euro rather than 6.0pt.

Why do you put the result into a dimension register?  Wouldn't it be
much more flexible, more convenient and much more general to put the
output into a token register?

   \newtoks\testtoks
   \rubycalc\testtoks{3*2}
   \the\testtoks

   Output (\the\testtoks causes):

   6.0

No need then to strip the "pt" and you have arbitrary resolution.  And
I can probably even get my 6.0 Euro.

  Reinhard
