Subscript
Encyclopedia : S : SU : SUB : Subscript
A subscript is a number, figure, or indicator that appears below the normal line of type, typically used in a formula, mathematical expression, or description of a chemical compound. Probably the most famous example of a subscript is the number 2 in the formula for the molecule of water: H2O.
Typographically, subscripts are set with a lower baseline and a smaller size than the other text. For example, to set H2O correctly, the 2 should be about two-thirds the size of the H and the O. This is done automatically in many text editing and word processing programs (such as Microsoft Word).
- In HTML and Wiki syntax, subscript text is produced by putting it inside the tags
<sub>and</sub>. - Unicode defines subscript characters such as ₀ ₁ ₂ ₃ ₄ ₅ ₆ ₇ ₈ ₉ ₊ ₋ ₌ ₍ ₎ (₀ to ₎).
- In TeX's math mode (as used in MediaWiki), subscripts are typeset with the underscore _:
$X_$produces [X_].
