\n
nand<\/code> and nor<\/code>. (documentation<\/a>)<\/li>\n\n\n\nisnan<\/code> and withintolerance<\/code> now also work on complex numbers. (code<\/a>)<\/li>\n\n\n\nsum<\/code> and prod<\/code> are now also defined on integers, decimals and rationals, and lcm<\/code> and gcd<\/code> on integers, so they’ll return the appropriate data type instead of always returning number<\/code> values. (code<\/a>)<\/li>\n\n\n\nand<\/code>, or<\/code>, implies<\/code>, nand<\/code> and nor<\/code> are evaluated lazily, so if the left-hand argument determines the result, the right-hand side isn’t evaluated. (issue<\/a>)<\/li>\n\n\n\nvariable_generation_run_number<\/code>, to help with deterministically generating variable sets that satisfy a condition. (documentation<\/a>)<\/li>\n<\/ul>\n\n\n\nBug fixes<\/h3>\n\n\n\n
\n
Numbas.loadStandaloneScript<\/code> takes a type<\/code> parameter. (code<\/a>)<\/li>\n\n\n\ndom<\/code> binding handler so it copes with a list of nodes, such as a list of images produced in marking feedback. (code<\/a>)<\/li>\n\n\n\ndatetime<\/code> binding handler deals with empty values. (code<\/a>)<\/li>\n\n\n\nExamDisplay.advance<\/code> and reverse<\/code>. (code<\/a>)<\/li>\n\n\n\nNumbas.controls<\/code> when working with the pre-2025 default theme. (code<\/a>)<\/li>\n\n\n\n\\var<\/code> and \\simplify<\/code> always put braces around the produced TeX. (code<\/a>)<\/li>\n\n\n\n\\_<\/code> in TeX. (code<\/a>)<\/li>\n\n\n\nfont-size-adjust: none<\/code>. (code<\/a>)<\/li>\n\n\n\nfont-size-adjust<\/code> style is not applied to MathJax output. (issue<\/a>)<\/li>\n\n\n\n<script><\/code> literally in their source. (issue<\/a>)<\/li>\n\n\n\nold-default-2024<\/code> theme, fixed loading the storage<\/code> attribute from <numbas-exam><\/code>. (code<\/a>)<\/li>\n\n\n\ncolor: inherit<\/code> to match the surrounding text. (issue<\/a>)<\/li>\n\n\n\nPromise.withResolvers<\/code>, to ensure compatibility with older browsers. (code<\/a>)<\/li>\n\n\n\nset<\/code> function. (code<\/a>)<\/li>\n\n\n\nScope.getFunction<\/code> applies function synonyms. (code<\/a>)<\/li>\n\n\n\nshadowRoot<\/code>. (code<\/a>)<\/li>\n\n\n\nnumbas-mathjax<\/code> script, so new versions are fetched instead of using an old version from the browser cache. (code<\/a>)<\/li>\n\n\n\nNumbas.math.Fraction<\/code> checks for denominator undefined<\/code>, using a default of 1. (code<\/a>)<\/li>\n\n\n\nExtensions<\/h3>\n\n\n\n

\n
aligned<\/code>.<\/li>\n\n\n\ntext<\/code> function now takes an optional angle argument. (code<\/a>)<\/li>\n\n\n\nxmlns<\/code> attribute. (code<\/a>)<\/li>\n\n\n\ngrid<\/code> function which lays subdiagrams out on a grid. (code<\/a>)<\/li>\n\n\n\n\n
text-align: start<\/code>. (code<\/a>)<\/li>\n\n\n\nFraction<\/code> data type from the Numbas core, instead of its own version. (code<\/a>)<\/li>\n\n\n\n\n
Numbas editor<\/a><\/h2>\n\n\n\n
\n
<numbas-exam><\/code> element. (documentation<\/a>)<\/li>\n\n\n\nvariable_overrides<\/code> list not being long enough. (code<\/a>)<\/li>\n\n\n\n\\begin{\u2026}<\/code> environments. (code<\/a>)<\/li>\n\n\n\n
