I would like to have a \smile
symbol under a plus symbol. What I have so far is
\newcommand{\pluss}{\raisebox{-.5ex}{\,$\overset{\textstyle{\raisebox{-0.5ex}{$+$}}}{\smile}$}\,}
However, I would like to have the plus further below. I tried to do this via the \raisebox
command (as you can see). This works to some extend, but when I go further than -0.5ex, the whole thing will go down instead of just the plus symbol.
Can anyone help, please?
\newcommand{\pluss}{\,\text{\raisebox{-.4ex}{$\smile$}}\text{\hspace{-1.3ex}\raisebox{.4ex}{$+$}}\,}
\mathbin
and\mathrel
have slightly different spacing. So, when I say binary or relational in this context, I’m referring to the TeX character class—you’re certainly correct that, mathematically, relational operators are binary! If you like how the answers look, you don’t need to modify them. In other cases, you might want to wrap the symbols you generate in something like\mathrel{\SomeRelationalSymbol}
.
