After a bit of discussion over on TiddlyTalk <https://talk.tiddlywiki.org/t/what-are-current-options-for-plain-arithmetic/2699/12>, I've resolved a security issue and feel good enough about the little solution for lengthy/complex (but primitive only) arithmetic expressions.
In this sample TiddlyWiki instance <https://cjveniot.neocities.org/TiddlyWikiEvalThisMacro.html>, you'll find the following two tiddlers needed: - Eval.js (the javascript eval function, locked to only allow the characters (excluding the double quotes) "0123456789 ()+-*/%" - EvalThis tiddler with the EvalThis macro. Although I can't stand javascript, I am not fussy about TiddlyWiki filter operations for lengthy/complex basic arithmetic, and not really fond of bringing in any of the powerful plugins out there when I don't need that much oomph. Some sample macro references: ` <<EvalThis "(100 + 2) / (9 - 1)">> <<EvalThis "59 % 3">> <<EvalThis "5**3">> <<EvalThis "( {{!!a}} * {{!!b}} ) / 2">> <$list filter="[range[25]]"> {{!!title}} / 2 = <<EvalThis "{{!!title}} / 2">><br> </$list> ` -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
