U+00B3 Superscript Three
U+00B3 was added in Unicode version 1.1 in 1993. It belongs to the block Latin-1 Supplement in the Basic Multilingual Plane.
This character is a Other Number and is commonly used, that is, in no specific script. The codepoint represents the digit 3. The character is also known as cubed.
The glyph is a superscript version of the glyph Digit Three. Its width in East Asian texts is determined by its context. It can be displayed wide or narrow. In bidirectional text it is written as European number from left to right. When changing direction it is not mirrored. If its East Asian Width is “narrow”, U+00B3 forms a word with similar characters, which prevents a line break inside it. Otherwise it allows line breaks around it, except in some numeric contexts.
The CLDR project calls this character “superscript three” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: cubed, superscript, three.
The Wikipedia has the following information about this codepoint:
In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 23 = 8 or (x + 1)3.
The cube is also the number multiplied by its square:
- n3 = n × n2 = n × n × n.
The cube function is the function x ↦ x3 (often denoted y = x3) that maps a number to its cube. It is an odd function, as
- (−n)3 = −(n3).
The volume of a geometric cube is the cube of its side length, giving rise to the name. The inverse operation that consists of finding a number whose cube is n is called extracting the cube root of n. It determines the side of the cube of a given volume. It is also n raised to the one-third power.
The graph of the cube function is known as the cubic parabola. Because the cube function is an odd function, this curve has a center of symmetry at the origin, but no axis of symmetry.
