Thus "H₂O" (using a subscript 2 character) is supposed to be identical to "H 2 O" (with subscript markup). In reality, many fonts that include these characters ignore the Unicode definition, and instead design the digits for mathematical numerator and denominator glyphs, [3] [4] which are aligned with the cap line and the baseline, respectively.
In symbolic form, the number of nucleons is denoted as a superscripted prefix to the chemical symbol (for example 3 He, 12 C, 13 C, 131 I, and 238 U). The letters m or f may follow the number to indicate metastable or fission isomers, as in 58m Co or 240f Pu. Subscripts and superscripts can also be used together to give more specific ...
Superscripts and Subscripts is a Unicode block containing superscript and subscript numerals, mathematical operators, and letters used in mathematics and phonetics. The use of subscripts and superscripts in Unicode allows any polynomial, chemical and certain other equations to be represented in plain text without using any form of markup like HTML or TeX.
Often used for finite fields, with a subscript to indicate the order. [26] Also represents a Hirzebruch surface or a free group, with a subscript to indicate the number of generators (or generating set, if infinite). U+1D53E: 𝔾 Represents a Grassmannian or a group, especially an algebraic group.
Centuries and millennia are written using ordinal numbers, without superscripts and without Roman numerals: the second millennium, the 19th century, a 19th-century book (see also Wikipedia:Manual of Style#Numbers as figures or words). Non-base-10 notations in non-computer-related articles use
The Unicode Standard encodes almost all standard characters used in mathematics. [1] Unicode Technical Report #25 provides comprehensive information about the character repertoire, their properties, and guidelines for implementation. [1]
By default, a space of approximately 1/6 em is added after the symbol to prevent the oblique symbol from overlapping the upright superscript or subscript. To suppress this spacing, give the optional s=0 parameter (any value other than zero is ignored); the s parameter is ignored if the first argument (for the base symbol) is blank.
On a computer running the Microsoft Windows operating system, many special characters that have decimal equivalent codepoint numbers below 256 can be typed in by using the keyboard's Alt+decimal equivalent code numbers keys. For example, the character é (Small e with acute accent, HTML entity code é) can be obtained by pressing Alt+1 3 0.
