Template:Tfrac/doc
- Note: The {{tfrac}} template is meant to be used within e.g. {{dfrac}}, {{root}}, {{sqrt}}, etc. to get a text style fraction.
The {{tfrac}} (text style fraction) mathematical formatting template and/or mathematical function template gives an HTML+CSS or a LaTeX formatted rational expression and/or the numerical result of the rational expression. The {{tfrac}} template gives a text style fraction, which displays it's numerator and denominator in script style. Compare with the {{dfrac}} template which gives a display style fraction whose numerator and denominator are shown in text style. Finally, the {{frac}} template gives either {{dfrac}} or {{tfrac}} (default).
Contents
Usage
- {{tfrac|numerator|denominator}}
or
- {{tfrac|numerator|denominator|format}}
where format is taken from
- htm: text style HTML+CSS tiny rational expression (default);
- HTM: display style HTML+CSS tiny rational expression;
- tex: text style LaTeX tiny rational expression;
- TEX: display style LaTeX tiny rational expression;
- #: numerical result.
As an alternative to using LaTeX rendered as PNG images (with either tex
or TEX
options), the html
or HTML
options will render the rational expression as HTML+CSS. You must use the {{tfrac}} template within the {{math}} template, which completes the formatting for mathematical expressions. (Do not use this option inside <math>...</math> tags.)
NOTE: To get rendered LaTeX, you must use the {{math}} template, since you cannot evaluate templates, parser functions or magic words inside <math>...</math> tags.
Minus sign issue
- Use {{op|-}} for minus sign (instead of -, the hyphen, hyphus or hyphen minus sign {{dash|hyphus}}) in the provided mathematical expression (because the border-top used to make the vinculum of radicals in the {{root}} template turns out to be made out of hyphens -, and we need to convert the {{dash|hyphus}} into proper {{dash|minus}} − signs for the HTML+CSS renderings).
- The {{op|-}} is replaced by a proper minus sign {{sym|-}} (i.e. {{dash|minus}}) in the {{math}} template for the HTML+CSS renderings (for LaTeX renderings, the {{dash|hyphus}} is properly turned into {{dash|minus}} by the LaTeX software).
