[reboot] Euler's number (e) should not be displayed as "E"

[Victor Thompson]

Euler's number[1] is typically referred to as "e". The symbol "E" is more typically used in "E notation" [2]. Additionally, the app uses a lower case "e" for "E notation". This is probably OK, but ideally the two should be swapped. "E" for "E notation" and "e" for "Euler's number."

Hi Victor, thanks for taking the time to try calculator reboot :-)

This is indeed a problem, because it could cause confusion - we will take a look!

In unicode there are special "Euler constant" which we could use instead of "E"

Unfortunately Euler constant U+2107 in Unicode is for:

My new proposal is to use Italic "e" letter instead of "E" (for displaying purpose):
