Formula Field with two decimal places only shows 1 decimal place

Formula Field with two decimal places only shows 1 decimal place

For sales orders or invoices we use prices with two decimal places.
However, when the calculated price is 1450.50 , the value is only shown as 1450.5

How can I force ZOHO CRM to always show 2 decimal places?

What I did:
- i added a custom field (formula), 2 decimal places
- in a template, i use this custom field via ${Invoices.myCustom1}
