Is it possible to change the percentage field in zoho crm , to put 3 decimals ?

Hello ,

I need to write 1,444 in the percentage field in zoho CRM.
However, I've noticed that there is a limitation of 2 decimals for this field. 

I've found out that if I replace this field with a Decimal one (.OO), I can choose to have 3 decimals. I've cheched that this field is not used in any formula. 

Is it the best solution or is there another one ? 

Regards,

Anne
