Talk:Int64

High(Int64)=9,223,372,036,854,775,807=(2^63)-1. Note the minus 1.
Also I think a closing bracket (]) is missing from the text inside the math markup? --Bart (talk) 23:10, 15 August 2020 (CEST)

Err, no. It’s a half-open interval. It’s correct. Confer terminology for intervals. Kai Burghardt (talk) 07:47, 16 August 2020 (CEST)

Well, that's why I said "I think". I suspect not may people really understand this math expression. — Preceding unsigned comment added by Bart (talk • contribs) 2020-08-16T13:04:01‎

Ok, there was a question mark though. Anyway, you can say this about pretty much everything: What does “∩” mean? What is ℤ? What is 2⁶³? It’s just, that’s basic stuff taught within the first four weeks of any college-level calculus course. And if you didn’t go to college, the written out numbers are given there, too. But feel free to change it. I prefer brevity. Kai Burghardt (talk) 21:03, 16 August 2020 (CEST)

Well, I didn't take calculus. Just the 2^63 caught my eye. It's fine with me. --Bart (talk) 21:21, 16 August 2020 (CEST)
