PDFMonkey provides two filters that help with formatting numbers: with_delimiter and format.

with_delimiter

{{12345.67 | with_delimiter, delimiter: ' ', separator: ',' }}€
12 345,67€

£{{12345 | with_delimiter, precision: 2}}
£12,345.00

In most cases the last one should be enough as is gives a way to specify the decimal delimiter, the thousands separator and the precision (number of digits after the decimal delimiter).

{{12345678 | with_delimiter}}
12,345,678

{{'123456' | with_delimiter}}
123,456

{{12345678.05 | with_delimiter}}
12,345,678.05

{{12345678 | with_delimiter, delimiter: '.'}}
12.345.678

{{12345678 | with_delimiter, delimiter: ','}}
12,345,678

{{12345678 | with_delimiter, delimiter: ',', precision: 2}}
12,345,678.00

{{12345678.05 | with_delimiter, separator: ' '}}
12,345,678 05

{{12345678.05 | with_delimiter, delimiter: ' ', separator: ','}}
12 345 678,05

{{'123a' | with_delimiter}}
123a

format

For more rare and advanced cases, you may need format as it provides ways to pad numbers, conditionally include decimals, etc.

{{5 | format: "%05d"}}
00005

{{5 | format: "%08.3f"}}
0005.000

{{5 | format: "%.2f"}}
5.00

{{5.1234 | format: "%.2f"}}
5.12

This filter is based on the Ruby format method. You can learn more about all the possibilities in the dedicated documentation.
