Number Symbols

The following symbols are used in formatting numbers. They will be substituted for the placeholders in Number Patterns

For English regional locales where English is not the customary language (such as en_DE, ie, English as used in Germany), the number formats and date formats should follow what is used for English in that country, which tends to follow the British or American usage rather than the predominant language (eg, German). Consult with the English versions of prominent magazines or newspapers for guidance on usage.

Name English Example
decimal 2,345.67
decimal separator
group 2,345.67
grouping separator, typically for thousands
plusSign +23 *

the plus sign used with numbers

minusSign -23 * the minus sign used with numbers

The + and - symbols are intended for unary usage, and not for binary usage; thus represents either the positive number or a negative number. For example, in an operation 3 -(-2), the defined symbol would be used for the second minus sign, but not for the subtraction operator. Any directionality markers needed (e.g. <LRM>) to keep with the number should be included.
percentSign 23.4% * the percent sign (out of 100)
perMille 234 * the permille sign (out of 1000)
exponential 1.2E3 * used in computers for 1.2×10³.
superscriptingExponent1.2×103         human-readable format of exponential 
infinity * used in +∞ and -∞. 
nan NaN * "not a number". 
timeSeparator2:33 PM This symbol is currently not used for anything (and is only visible in SurveyTool at comprehensive level)  but may be retrieved by CLDR data consumers. It should match the time separator symbol actually used in Date/Time Patterns.

* – Doesn't typically need to be changed in translation.

Important: Review the examples on the right-side pane to ensure that all pattern and symbols are as expected.
