This gives an overview of how to specify number formats in ROB-EX. Numbers are constructed with a string that specifies a pattern for how the numbers should be formatted. ROB-EX has a default format used, which can be overridden for some LayoutItems and for some GUI items in Roles.xml. For more info, see Enable/Disable GUI elements.
The default ROB-EX number format pattern is: “0.00”, meaning that there is minimum 1 integer digit and exactly 2 fraction digits. This can be changed by changing the value of the key=default.numberFormat in the language properties file. For more info on modifying the language file, see Runtime language configuration.
Below are some examples of number format patterns and the result they give (the grouping and decimal separator are locale dependent, below examples illustrate the en_US format):
| Pattern | Unformatted value | Formatted value |
| 0.00 | 12345.600 | 12345.60 |
| 0.00 | 12345.6789 | 12345.68 |
|
12345.600 | 12345.6 |
|
12345.6789 | 12345.68 |
| 00.0# | 1.234 | 01.23 |
| 00.0# | 1.200 | 01.2 |
| #,###.# | 1234567.89 | 1,234,567.9 |
