模板:Intmath/doc

This template generates integral symbols using unicode, for inline {{math}} formulae as an alternative to LaTeX generated in <math>.

Parameters

The template has three parameters, applicable one by one:

1. Integral sign: Choose one of:
   • int for ∫ symbol is U+222B
   • iint for ∬ (double integral, U+222C),
   • iiint for ∭ (triple integral, U+222D),
   • oint for ∮ (contour integral, U+222E),
   • varointclockwise for ∲ (clockwise contour integral, U+2232),
   • ointctrclockwise for ∳ (anticlockwise contour integral, U+2233),
   • oiint for ∯ (closed surface integral, U+222F),
   • oiiint for ∰ (closed volume integral, U+2230).
   These match the LaTeX definitions exactly: please do not modify them for something more "convenient", thank you.
2. Subscript: Enter the subscript (symbol or short expression), for the lower limit or denoting an n-dimensional space or the (n − 1)- dimensional boundary.
3. Superscript: Enter the superscript (symbol or short expression) for the upper limit.

NB:

• Applying font-style: italic; or font-style: oblique; to the integral symbol has no effect in Firefox, it remains upright. E.g.

  <span style="font-style: italic;">∫</span> yields ∫;

  <span style="font-style: oblique;">∫</span> yields ∫.

• This template already includes {{su}}.
