Maybe it makes more sense to throw a RangeError (since 0 is outside the valid range). http://people.mozilla.org/~jorendorff/es6-draft.html#sec-15.11.6.2 Another option is to throw a TypeError? 89653 1 erik.arvidsson 2013-06-20 16:07:52 +0000 I guess the same issue applies to skewX and skewY 89654 2 dschulze 2013-06-20 16:20:21 +0000 The idea is to replace SVGMatrix with the interface CSSMatrix https://dvcs.w3.org/hg/FXTF/raw-file/tip/matrix/index.html It still needs approval from the CSS WG though. This would also get rid of the exception handling, since we try to avoid exceptions in general unless you do something forbidden nowadays. Also, I assume the old exception handling is based on SVG exceptions which got replaced by general DOM exception in SVG2. 89655 3 erik.arvidsson 2013-06-20 16:36:42 +0000 CSSMatrix does not document what happens when x or y is 0. 89656 4 dschulze 2013-06-20 17:16:25 +0000 (In reply to comment #3) > CSSMatrix does not document what happens when x or y is 0.

Some matrix values get undefined. Sorry, in general depends on the math of each function. Some values can get none-finit.
