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 ...
As of Unicode version 16.0, there are 155,063 characters with code points, covering 168 modern and historical scripts, as well as multiple symbol sets.This article includes the 1,062 characters in the Multilingual European Character Set 2 subset, and some additional related characters.
The most common superscript digits (1, 2, and 3) were included in ISO-8859-1 and were therefore carried over into those code points in the Latin-1 range of Unicode. The remainder were placed along with basic arithmetical symbols, and later some Latin subscripts, in a dedicated block at U+2070 to U+209F.
Use of a user-defined function sq(x) in Microsoft Excel. The named variables x & y are identified in the Name Manager. The function sq is introduced using the Visual Basic editor supplied with Excel. Subroutine in Excel calculates the square of named column variable x read from the spreadsheet, and writes it into the named column variable y.
Functional notation: if the first is the name (symbol) of a function, denotes the value of the function applied to the expression between the parentheses; for example, (), (+). In the case of a multivariate function , the parentheses contain several expressions separated by commas, such as f ( x , y ) {\displaystyle f(x,y)} .
During typesetting, individual sorts are picked from a type case with the right hand, and set from left to right into a composing stick held in the left hand, appearing to the typesetter as upside down. As seen in the photo of the composing stick, a lower case 'q' looks like a 'd', a lower case 'b' looks like a 'p', a lower case 'p' looks like ...
The character was designed for typewriters to add a grave accent to a (lower-case [a]) base letter, by overtyping it atop that letter. [1] On early computer systems, however, this physical dead key +overtype function was rarely supported, being functionally replaced by precomposed characters .
