I have two integers "clicks" and "views" and am trying to find what the ratio of clicks to views. This should be (and is on my calculator)
clicks / views * 100 (to get the percent) 3 / 356 * 100 = .842 %
<dtml-var expr="clicks/views"> Returns = 0
<dtml-var expr="clicks/views" fmt="%.6f"> Returns 0.00000
I don't know what is wrong. Anyone?
Welcome to Python (and generally, most programming languages) integer calculations where 1 / 2 is 0. Integer division will yield integer results. If one of the operands is float however, it'll give a float result. In other words, 1 / 2.0 is 0.5 You'll have to convert at least one of the two operands to a float for the above to yield a float: <dtml-var expr="clicks/float(views)"> -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------
