Comment on attachment 408250 [details] Patch I see that the code involves a lot of floating point division. Last time I checked, I believe floating point multiplication was significantly faster. Perhaps we can make some of this division be multiplication by calculating a reciprocal or by reorganizing expressions. Or perhaps this kind of micro-optimization thinking is not relevant to this code. r=me assuming the tests pass
