• Where did you see this symbol used? What was the context? – Argon Sep 10 '17 at 4:29
• Are you missing a font or something? – Batman Sep 10 '17 at 4:30
• @Argon It's linked in the question. I'll post the links again: en.wikipedia.org/wiki/Scientific_notation en.wikipedia.org/wiki/Template:Val – Wood Sep 10 '17 at 4:31
• I don't see that symbol on those pages. – Argon Sep 10 '17 at 4:33
• @Batman Maybe. If that's the case, I'll close the question. Any idea how to fix it? Do you not see the spade symbol? – Wood Sep 10 '17 at 4:33
