  3. Unicode character property - Wikipedia

    en.wikipedia.org/wiki/Unicode_character_property

    A Unicode character is assigned a unique Name (na). [1] The name is composed of uppercase letters Aโ€“Z, digits 0โ€“9, hyphen-minus and space.Some sequences are excluded: names beginning with a space or hyphen, names ending with a space or hyphen, repeated spaces or hyphens, and space after hyphen are not allowed.

    The correct number of sections for a fence is n โˆ’ 1 if the fence is a free-standing line segment bounded by a post at each of its ends (e.g., a fence between two passageway gaps), n if the fence forms one complete, free-standing loop (e.g., enclosure accessible by surmounting, such as a boxing ring), or n + 1 if posts do not occur at the ends ...

  5. Unicode input - Wikipedia

    en.wikipedia.org/wiki/Unicode_input

    Hex input of Unicode must be enabled. In Mac OS 8.5 and later, one can choose the Unicode Hex Input keyboard layout; in OS X (10.10) Yosemite, this can be added in Keyboard โ†’ Input Sources. Holding down โŒฅ Option, one types the four-digit hexadecimal Unicode code point and the equivalent character appears; one can then release the โŒฅ Option ...

    en.wikipedia.org/wiki/Half-precision_floating...

    ILM was searching for an image format that could handle a wide dynamic range, but without the hard drive and memory cost of single or double precision floating point. [5] The hardware-accelerated programmable shading group led by John Airey at SGI (Silicon Graphics) used the s10e5 data type in 1997 as part of the 'bali' design effort.

  7. Gray code - Wikipedia

    en.wikipedia.org/wiki/Gray_code

    Gray's patent introduces the term "reflected binary code" In principle, there can be more than one such code for a given word length, but the term Gray code was first applied to a particular binary code for non-negative integers, the binary-reflected Gray code, or BRGC.

    Historically, under PDP-6 monitor, [2] RT-11, VMS, and TOPS-10, [3] and in early PC CP/M 1 and 2 operating systems (and derivatives like MP/M) it was necessary to explicitly mark the end of a file (EOF) because the native filesystem could not record the exact file size by itself; files were allocated in extents (records) of a fixed size, typically leaving some allocated but unused space at the ...

  9. Superscripts and Subscripts - Wikipedia

    en.wikipedia.org/wiki/Superscripts_and_Subscripts

    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.
