    Here the 'IEEE 754 double value' resulting of the 15 bit figure is 3.330560653658221E-15, which is rounded by Excel for the 'user interface' to 15 digits 3.33056065365822E-15, and then displayed with 30 decimals digits gets one 'fake zero' added, thus the 'binary' and 'decimal' values in the sample are identical only in display, the values ...

  3. Whitespace character - Wikipedia

    en.wikipedia.org/wiki/Whitespace_character

    In some cases, spaces are shown simply as blank space; in other cases they may be represented by an interpunct or other symbols. Many different characters (described below) could be used to produce spaces, and non-character functions (such as margins and tab settings) can also affect whitespace.

  4. Braille pattern dots-0 - Wikipedia

    en.wikipedia.org/wiki/Braille_pattern_dots-0

    In all braille systems, the braille pattern dots-0 is used to represent a space or the lack of content. [1] In particular some fonts display the character as a fixed-width blank. However, the Unicode standard explicitly states that it does not act as a space, [ 2 ] a statement added in response to a comment that it should be treated as a space.

  5. Box-drawing characters - Wikipedia

    However, they are still useful for command-line interfaces and plaintext comments within source code. Some recent embedded systems also use proprietary character sets, usually extensions to ISO 8859 character sets, which include box-drawing characters or other special symbols.

  6. Indentation style - Wikipedia

    en.wikipedia.org/wiki/Indentation_style

    In computer programming, indentation style is a convention, a.k.a. style, governing the indentation of blocks of source code.An indentation style generally involves consistent width of whitespace (indentation size) before each line of a block, so that the lines of code appear to be related, and dictates whether to use space or tab characters for the indentation whitespace.

  7. Delimiter-separated values - Wikipedia

    en.wikipedia.org/wiki/Delimiter-separated_values

    Delimiter collision is a problem that occurs when a character that is intended as part of the data gets interpreted as a delimiter instead. Comma- and space-separated formats often suffer from this problem, since in many contexts those characters are legitimate parts of a data field.

  8. Tab-separated values - Wikipedia

    en.wikipedia.org/wiki/Tab-separated_values

    The IANA media type standard for TSV achieves simplicity by simply disallowing tabs within fields. [4]Since the values in the TSV format cannot contain literal tabs or newline characters, a convention is necessary for lossless conversion of text values with these characters.

  9. Halfwidth and Fullwidth Forms (Unicode block) - Wikipedia

    Code chart ∣ Web page Note : [ 1 ] [ 2 ] [ 3 ] Halfwidth and Fullwidth Forms is a Unicode block U+FF00–FFEF, provided so that older encodings containing both halfwidth and fullwidth characters can have lossless translation to/from Unicode.
