MYSQL Timestampdiff output formatting last two decimals -

-

simple question

what best way change output displays last 2 decimals?

select avg(timestampdiff(hour, start_it,start_qa)

so output of '13.2500' displays '13.25'.

thanks help.

normally, in application layer. if insist on doing in database, can use format():

select format(avg(timestampdiff(hour, start_it,start_qa), 2)
