Binomial coefficients: The brackets stay small (usual size like in plain text), here's my code: \starttext \startformula {a\choose b} \stopformula \stoptext
This is currently an issue with opentype math fonts: luatex doesn't know what the values of \Umathfractiondelsize should be. For a workaround: explicitly setting \Umathfractiondelsize\textstyle = 12.12pt \Umathfractiondelsize\displaystyle = 28.68pt will set up values that closely mimic "cmsy10 at 12pt" Ulrik Vieth (who is in CC) proposes to use DelimitedSubFormulaMinHeight in non-display modes, but the DelimitedSubFormulaMinHeight in Cambria Math is 3000/2048 * <atsize> == 17.58pt, which also doesn't seem right. Since Hans converts everything to OpenType MathConstants format, perhaps I should just add two more named entries to be parsed in the MathConstants table? Best wishes, Taco
