When using XSLT’s format-number() function to format a decimal, consider using a zero in the least significant place of the decimal part of your format string. This will allow a number with a 0 integer part to display correctly.
For example:
| Number | format-number using #,### | format-number using #,##0 |
|---|---|---|
| 12345 | 12,345 | 12,345 |
| 5 | 5 | 5 |
| No output! |
This also applies to decimals:
| Number | format-number using #.00 | format-number using 0.00 |
|---|---|---|
| 5 | 5.00 | 5.00 |
| .00 (Note no leading 0) | 0.00 | |
| 0.1234 | .12 (Note no leading 0) | 0.12 |
