Artoria2e5 has just created a new issue for https://github.com/w3c/fxtf-drafts: == [filter-effects-1] inconsistent number of decimal places for hueRotate matrix == In https://drafts.fxtf.org/filter-effects/#attr-valuedef-type-huerotate (actually scroll down a little), we see: >For type="hueRotate", [values](https://drafts.fxtf.org/filter-effects/#element-attrdef-fecolormatrix-values) is a single one real number value (degrees). A [hueRotate](https://drafts.fxtf.org/filter-effects/#attr-valuedef-type-huerotate) operation is equivalent to the following matrix operation: >MML >where the terms a00, a01, etc. are calculated as follows: > feColorMatrix03.mml > Thus, the upper left term of the hue matrix turns out to be: > feColorMatrix04.mml The issue is that the two MMLs, https://github.com/w3c/fxtf-drafts/blob/1c75a54c68e937275f55ce3990def0ddc4b3b7e4/filter-effects/mathml/feColorMatrix03.mml and https://github.com/w3c/fxtf-drafts/blob/1c75a54c68e937275f55ce3990def0ddc4b3b7e4/filter-effects/mathml/feColorMatrix04.mml, disagree on their number of decimal places. 03 says "0.213, 0.787", while 04 gives "0.2127, 0.7873".
