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:

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.
Subscript: Enter the subscript (symbol or short expression), for the lower limit or denoting an n-dimensional space or the (n − 1)- dimensional boundary.
Superscript: Enter the superscript (symbol or short expression) for the upper limit.

NB:

Applying italics to the integral symbol has no effect in Firefox, it remains upright.
This template already includes {{su}}.
