π
damn! I think I've got it!
C99 -- click on the link suggested by Region Philbis up above. The very first answer to the questions tells you how to do it. Just type ampersand(&) + pi + semicolon ( ; ). No spaces. You'll get π
I doubt it, his method for writing pi produces it immediately on his screen as it's typed, the HTML entity doesn't work till it becomes HTML and it can confuse anyone who is running into the distinction for the first time.
