How can i format data number and dynamic output on email alerting?

Plugins Alerting
1

Hello,

i have a problem i would like to format the numerical output of the disk usage percentage values ​​to something more readable (currently: 0.9261000156402588 i would like it to become 92.0), also you can set a loop that prints all the results in the mail? For now I have found an inelegant method …
This is the alert json extracted from the API call:
