====== Appendix C. Number Format in Java Programming Language ======

The following section describes the format of the number used in the Java Programming Language. This format can be used for attributes of Number type – see [[docs:2500_config_apps:0700_add_edit_attributes:0300_number_attributes|Setting Properties of Number Attributes]].

The string representing the number format has the following form: 

''positive-pattern[;negative-pattern]''



If the negative pattern is omitted, negative numbers are formatted using the positive pattern with a “-“ character prepended to the result. Each pattern has the following form: 

''[prefix]integer[.fraction][suffix]''



The following symbols are significant in the pattern string. 

^Symbol^Description^
| 0|A digit|
| #|A digit where 0 is not shown|
| .|A placeholder for a decimal separator|
| ,|A placeholder for a grouping separator|
| ;|The format separator|
| -|The default negative prefix|
| %|Multiplies value by 100 and shows as a percentage|

Any characters other than these special characters can appear in the prefix or the suffix. A single quote can be used to escape a special character, if you need to use one of these symbols in a prefix or a suffix. 

For example, the pattern string for U.S. currency values is: 

''$#,##0.00;($#,##0.00)''



This indicates that a $ character is prepended to all formatted values. The grouping separator character , is inserted every three digits. Exactly two digits after the decimal place are always shown. Negative values are shown in parentheses. Thus, the value -1234.56 produces output like: 

''($1,234.56)''
