Example: $\spadesuit 3.5×10^2$
The Wikipedia page about scientific notation (permalink) didn't help. Neither did the "Val" template page (permalink).
Here's a screenshot of what shows up for me:

1Where did you see this symbol used? What was the context? – Argon Sep 10 '17 at 04:29

Are you missing a font or something? – Batman Sep 10 '17 at 04:30

@Argon It's linked in the question. I'll post the links again: https://en.wikipedia.org/wiki/Scientific_notation https://en.wikipedia.org/wiki/Template:Val – Wood Sep 10 '17 at 04:31

1I don't see that symbol on those pages. – Argon Sep 10 '17 at 04:33

@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 04:33

You are probably missing a font that displays "Miscellaneous Technical" symbols in Unicode. The Wikipedia page has this boxed note in the right hand margin:
This article contains Unicode "Miscellaneous Technical" characters. Without proper rendering support, you may see question marks, boxes, or other symbols instead of "₁₀" (Decimal Exponent Symbol U+23E8 TTF).
