A delimited text file is a text file used to store data, in which each line represents a single book, company, or other thing, and each line has fields separated by the delimiter. [3] Compared to the kind of flat file that uses spaces to force every field to the same width, a delimited file has the advantage of allowing field values of any length.
The CSV file format is one type of delimiter-separated file format. [2] Delimiters frequently used include the comma, tab, space, and semicolon. Delimiter-separated files are often given a ".csv" extension even when the field separator is not a comma. Many applications or libraries that consume or produce CSV files have options to specify an ...
A delimiter is a sequence of one or more characters for specifying the boundary between separate, independent regions in plain text, mathematical expressions or other data streams. [ 1 ] [ 2 ] An example of a delimiter is the comma character, which acts as a field delimiter in a sequence of comma-separated values .
In European languages, large numbers are read in groups of thousands, and the delimiter—which occurs every three digits when it is used—may be called a "thousands separator". In East Asian cultures , particularly China , Japan , and Korea , large numbers are read in groups of myriads (10 000s) but the delimiter commonly separates every ...
If the individual items of a list are long, complex, affixed with description, or themselves contain commas, semicolons may be preferred as separators, and the list may be introduced with a colon. In news headlines, a comma might replace the word "and", even if there are only two items, in order to save space, as in this headline from Reuters: [11]
In the figure, the fraction 1/9000 is displayed in Excel. Although this number has a decimal representation that is an infinite string of ones, Excel displays only the leading 15 figures. In the second line, the number one is added to the fraction, and again Excel displays only 15 figures. In the third line, one is subtracted from the sum using ...
The quotient space / where the natural numbers on the real line are identified as a single point is not first countable. [1] However, this space has the property that for any subset and every element in the closure of , there is a sequence in converging to . A space with this sequence property is sometimes called a Fréchet–Urysohn space ...
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.
