how can I get a float to always print two decimal places? Thanks, Jamie
maybe with sprintf("%.2f", 0.123456)
=> "0.12"

Thanks, that did it. Is this the preferred syntax?
<%= sprintf("%.2f",@item.distance) %>

You can also use String#% (i.e. the modulo operator), which gives the same result: <%= "%.2f" % @item.distance %> Looks cleaner (imho) when there''s only one value involved, but multiple values have to be put in an array, which looks a bit messy. I tend to use String#% when there''s only one value involved and sprintf for multiple values. //samuel 2005-01-30 kl. 01.02 skrev Jamie Orchard-Hays:> Thanks, that did it.
