Dear Community!
I'm trying to convert a number to a string, but my attempts have not yet been successful.

There is an number field, but when you try to send an email or comment with this value, it is converted to a mathematical format - 1.23123123123E11
Is it possible to somehow convert the field to a string?
I tried the following options, but none of them worked.
Number: {{issue.fields.customfield_10000.toNumber().toString()}}
Number2: {{issue.fields.customfield_10000}}
Number3 {{issue.fields.customfield_10000.toString()}}
Number4: {{issue.fields.customfield_10000.tostring}}
Number5: {{issue.fields.customfield_10000.asString}}
Number6: {{issue.fields.customfield_10000.asString()}} 
Thanks in advance!
