I''m using this: <% words = article.content.split(/ /) %> <%= words[0..20] %> to (ostensibly) split a paragraph into component words, with spaces in between, then print to html only the first 20 items, words and spaces.

I''m using Oracle to back my Rails app, and I noticed somewhere along the line that if my ID is declared as NUMBER then it wants to show up as "123.0" whenever I ask for it (i.e. link_to and other things).
