U+2230 Volume Integral

U+2230 was added in Unicode version 1.1 in 1993. It belongs to the block U+2200 para U+22FF Mathematical Operators in the U+0000 para U+FFFF Basic Multilingual Plane.

This character is a Puntuación matemática and is commonly used, that is, in no specific script.

The glyph is a compatibility composition of the glyphs Glifo para U+222E Contour Integral, Glifo para U+222E Contour Integral, Glifo para U+222E Contour Integral. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is mirrored. The word that U+2230 forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

El Wikipedia tiene la siguiente información acerca de este punto de código:

In mathematics (particularly multivariable calculus), a volume integral (∭) is an integral over a 3-dimensional domain; that is, it is a special case of multiple integrals. Volume integrals are especially important in physics for many applications, for example, to calculate flux densities, or to calculate mass from a corresponding density function.
