Grafana alerting: Looking for exact value

Hi Dawid,
Hope you have a great start to the new year!
I am working on SSL certificate expiry alert in Grafana.
I get the exact number of days that is left for expiry.
But I wanted it in description as annotation.
That is where I am currently stuck.

instead of {{$B}}, i want it to show the value as 371 (no decimal points)

Do you have a suggestion?
