# If you use the jsMath control panel, it will add parameters to the URL, which interfere with TiddlyWiki's save function. The jsMath options are stored in a cookie, so after setting them it is safe to reload your tiddlywiki file. (A fix for this has been submitted, and hopefully will be in tiddlywiki 2.0.4)\n# The font browser font size and alignment does not always match the math. (anyone have an idea to fix this?)\n# The use of certain math characters (like \s\ssqrt) causes firefox 1.5.0.1 to crash. Firefox 1.5 does not have this problem, nor do more recent nightly builds of firefox from mozilla.org. So it seems this is a firefox bug and is already fixed. (Though if you are able to discover a workaround, please let me know!)

You may customize the number of significant figures displayed, as well as "normalize" numbers so that {{{47392.387e9}}} is displayed as 47392.387e9.\n!Installation\nInstall the Requirements, above, add this tiddler to your tiddlywiki, and give it the {{{systemConfig}}} tag.\n!History\n* 1-Feb-06, version 1.0, Initial release\n!Code\n***/\n//{{{\nconfig.formatters.push({\n name: "scientificNotation",\n match: "\s\sb[0-9]+\s\s.[0-9]+[eE][+-]?[0-9]+\s\sb",\n element: "span",\n className: "math",\n normalize: true, // set to 'true' to convert numbers to X.XXX \stimes 10^{y}\n sigfigs: 3, // with this many digits in the mantissa\n handler: function(w) {\n var snRegExp = new RegExp("\s\sb([0-9]+(?:\s\s.[0-9]+)?)[eE]([-0-9+]+)\s\sb");\n var mymatch = snRegExp.exec(w.matchText);\n var mantissa = mymatch[1];\n var exponent = parseInt(mymatch[2]);\n // normalize the number.\n if(this.normalize) {\n mantissa = parseFloat(mantissa);\n while(mantissa > 10.0) {\n mantissa = mantissa / 10.0;\n exponent++; \n }\n while(mantissa < 1.0) {\n mantissa = mantissa * 10.0;\n exponent--;\n }\n var sigfigsleft = this.sigfigs;\n mantissa = parseInt(mantissa) + "." + (Math.round(Math.pow(10,this.sigfigs-1)*mantissa)+"").substr(1,this.sigfigs-1);\n }\n var e = document.createElement(this.element);\n e.className = this.className;\n if(exponent == 0) {\n e.appendChild(document.createTextNode(mantissa));\n } else {\n e.appendChild(document.createTextNode(mantissa + "\s\stimes 10^{" + exponent + "}"));\n }\n w.output.appendChild(e);\n }\n});\n//}}}

/***\n|Name|Plugin: jsMath|\n|Created by|BobMcElrath|\n|Email|my first name at my last name dot org|\n|Location|http://bob.mcelrath.org/tiddlyjsmath.html|\n|Version|1.5.1|\n|Requires|[[TiddlyWiki|http://www.tiddlywiki.com]] ≥ 2.0.3, [[jsMath|http://www.math.union.edu/~dpvc/jsMath/]] ≥ 3.0|\n!Description\nLaTeX is the world standard for specifying, typesetting, and communicating mathematics among scientists, engineers, and mathematicians. For more information about LaTeX itself, visit the [[LaTeX Project|http://www.latex-project.org/]]. This plugin typesets math using [[jsMath|http://www.math.union.edu/~dpvc/jsMath/]], which is an implementation of the TeX math rules and typesetting in javascript, for your browser. Notice the small button in the lower right corner which opens its control panel.\n!Installation\nIn addition to this plugin, you must also [[install jsMath|http://www.math.union.edu/~dpvc/jsMath/download/jsMath.html]] on the same server as your TiddlyWiki html file. If you're using TiddlyWiki without a web server, then the jsMath directory must be placed in the same location as the TiddlyWiki html file.\n\nI also recommend modifying your StyleSheet use serif fonts that are slightly larger than normal, so that the math matches surrounding text, and \s\ssmall fonts are not unreadable (as in exponents and subscripts).\n{{{\n.viewer {\n line-height: 125%;\n font-family: serif;\n font-size: 12pt;\n}\n}}}\n\nIf you had used a previous version of [[Plugin: jsMath]], it is no longer necessary to edit the main tiddlywiki.html file to add the jsMath <script> tag.
