Is there any way to get the U+225F ≟ questioned equals sign in math formatting?

I have been trying simply copying it in, but it looks rather small, and I'm wondering if there is a way to produce it using the conventional math formatting.

You can get that symbol by using the stackrel()() function--read this answer for a description of how that function works--but the result is not that different from what you get by simply copying the character.

So, you could write something like this

  • without the hashtags

stackrel(\ ? )(\ =)

  • with the hashtags

#stackrel(\ ? )(\ =)#

The "\" characters are added in there to ensure that the #=# sign and the #?# are aligned properly.

So this is pretty much all you can hope for using the math formatting. At this point, I'd say that it comes down to what approach you prefer, i.e. using this syntax or copying the character directly.
