    number of characters and number of bytes, respectively COBOL: string length string: a decimal string giving the number of characters Tcl: ≢ string: APL: string.len() Number of bytes Rust [30] string.chars().count() Number of Unicode code points Rust [31]

  3. Pivot table - Wikipedia

    en.wikipedia.org/wiki/Pivot_table

    Column labels are used to apply a filter to one or more columns that have to be shown in the pivot table. For instance if the "Salesperson" field is dragged to this area, then the table constructed will have values from the column "Sales Person", i.e., one will have a number of columns equal to the number of "Salesperson". There will also be ...

  4. UTF-16 - Wikipedia

    en.wikipedia.org/wiki/UTF-16

    Code points greater than or equal to 2 16 ("above the BMP") are encoded using two 16-bit code units. These two 16-bit code units are chosen from the UTF-16 surrogate range 0xD800–0xDFFF which had not previously been assigned to characters. Values in this range are not used as characters, and UTF-16 provides no legal way to code them as ...

    This is the minimum number of characters needed to encode a 32 bit number into 5 printable characters in a process similar to MIME-64 encoding, since 85 5 is only slightly bigger than 2 32. Such method is 6.7% more efficient than MIME-64 which encodes a 24 bit number into 4 printable characters.

    In SGML, HTML and XML documents, the logical constructs known as character data and attribute values consist of sequences of characters, in which each character can manifest directly (representing itself), or can be represented by a series of characters called a character reference, of which there are two types: a numeric character reference and a character entity reference.

  7. Counting - Wikipedia

    en.wikipedia.org/wiki/Counting

    Number blocks, which can be used for counting. Counting is the process of determining the number of elements of a finite set of objects; that is, determining the size of a set. . The traditional way of counting consists of continually increasing a (mental or spoken) counter by a unit for every element of the set, in some order, while marking (or displacing) those elements to avoid visiting the ...

  8. Character (computing) - Wikipedia

    en.wikipedia.org/wiki/Character_(computing)

    Furthermore, a "character" may require more than one code point (for instance with combining characters), depending on what is meant by the word "character". The fact that a character was historically stored in a single byte led to the two terms ("char" and "character") being used interchangeably in most documentation.

  9. Unicode subscripts and superscripts - Wikipedia

    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.
