How You Format Numeric Separators and Decimal Precision for Numeric Data
You can use the function <?format-number:NUMERIC_VARIABLE;
’9G999D99'?>
where G stands for the position of the comma (,) and D stands for
position of the decimal. For example:
<?format-number:COMP_1_COMPENSATION_AMOUNT; ’9G999D99'?>
If the value of the variable COMP_1_COMPENSATION_AMOUNT is 1234.5678, the above expression will display it as “1,234.57” after rounding the numeric data to two decimal places.
Alternatively, you can also make use of form field options.
