Rough equality has a number of highly undesirable features - it's not transitive, it breaks with zoom etc. 451110 2 eae 2011-08-15 10:22:02 -0700 No firm decision yet, we have a prototype running on trunk that we are running a set of tests against to see if it's feasible to use floats throughout and help us discover problems. We're currently leaning towards using floats as both javascript and the graphics sub system operates on floating point but we'll revisit this before committing to go down that path. This bug is for tracking places where we might need to change how we do comparisons if we decide to go with floats. 494315 3 eae 2011-11-01 17:04:47 -0700 No longer applicable as we decided to go with fixed point.
