U+2298 CIRCLED DIVISION SLASH

U+2298 was added to Unicode in version 1.1 (1993). It belongs to the block Mathematical Operators in the Basic Multilingual Plane.

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

The glyph is not a composition. It has a Neutral East Asian Width. In bidirectional context it acts as Other Neutral and is mirrored. Its corresponding mirrored glyph is ⦸. In text U+2298 behaves as Alphabetic regarding line breaks. It has type Other for sentence and Other for word breaks. The Grapheme Cluster Break is Any.

The Wikipedia has the following information about this codepoint:

In mathematics, especially in elementary arithmetic, division (denoted ÷ or / or —) is an arithmetic operation. Specifically, if b times c equals a, written:

a = b × c

where b is not zero, then a divided by b equals c, written:

÷

For instance,

6 ÷ 3 = 2

since

3 × 2 = 6.

In the above expressions, a is called the dividend, b is called the divisor, and c is called the quotient; in the expression or a is also called the numerator and b is also called the denominator.

Conceptually, division of integers can be viewed in either of two distinct but related ways quotition and partition:

  • Partitioning involves taking a set of size a and forming b groups that are equal in size. The size of each group formed, c, is the quotient of a and b.
  • Quotition, or quotative division (also sometimes spelled quotitive) involves taking a set of size a and forming groups of size b. The number of groups of this size that can be formed, c, is the quotient of a and b. (Both divisions give the same result because multiplication is commutative.)

Teaching division usually leads to the concept of fractions being introduced to school pupils. Unlike addition, subtraction, and multiplication, the set of all integers is not closed under division. Dividing two integers may result in a remainder. To complete the division of the remainder, the number system is extended to include fractions or rational numbers as they are more generally called.
