U+2A0C Quadruple Integral Operator

U+2A0C was added in Unicode version 3.2 in 2002. It belongs to the block U+2A00 to U+2AFF Supplemental Mathematical Operators in the U+0000 to U+FFFF Basic Multilingual Plane.

This character is a Math Symbol and is commonly used, that is, in no specific script.

The glyph is a compatibility composition of the glyphs Integral, Integral, Integral, 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+2A0C forms with similar adjacent characters prevents a line break inside it. The glyph can be confused with one other glyph.

Wikipedia ma następujące informacje na temat tej współrzędnej kodowej:

In mathematics (specifically multivariable calculus), a multiple integral is a definite integral of a function of several real variables, for instance, f(x, y) or f(x, y, z).
Integrals of a function of two variables over a region in $R^{2}$ (the real-number plane) are called double integrals, and integrals of a function of three variables over a region in $R^{3}$ (real-number 3D space) are called triple integrals. For multiple integrals of a single-variable function, see the Cauchy formula for repeated integration.
