My paper is accepted at MNRAS and in the stage of editing.
There is a section where I wrote an equation using the Greek letter π as to indicate the mathematical constant π.
The editor wrote:
Author: When used to mean the numerical value
3.14, the Greek letter
pimust always be written in roman. Please check all the notations throughout the text carefully
I think this request is canned, so I doubt there is any typo or similar here.
What exactly is π in roman? Shouldn't it be written in Greek? Is it a mistake of the editor or a misunderstanding from my side?
