[Tex/LaTex] How to typeset the symbol “^” (caret/circumflex/hat)

symbols

I need to display the symbol '^'

d <- dist(fascores, method = "euclidean")^2

How do I do that?

Best Answer

You can use

in text-mode (needs \textrm or similar in math-mode)
- \textasciicircum or
- \^{},
in math-mode
- \hat{} (only this produces a circumflex),
- \widehat{}, or
- \wedge (∧).

in a verb-like manner

\string^,
\char`\^,

\verb!^!:

\verb!d <- dist(fascores, method = "euclidean")^2!

Overview

Code

\documentclass{standalone}
\usepackage{upquote}% getting the right grave ` (and not ‘)!
\begin{document}
\begin{tabular}{lcc}
    Input                   &       Text       &                 Math                  \\ \hline
    \verb|\string^|         &     \string^     &              $\string^$               \\
    \verb|\char`\^|         &     \char`\^     &              $\char`\^$               \\
    \verb|\verb!^!|         &     \verb!^!     &              $\verb!^!$               \\ \hline
    \verb|\textasciicircum| & \textasciicircum &                  ---                  \\
    \verb|\^{}|             & \^{} (e.g. \^a)  &                  ---                  \\ \hline
    \verb|\hat{}|           &       ---        &       $\hat{}$ (e.g. $\hat a$)        \\
    \verb|\wedge|           &       ---        &      $\wedge$ (e.g. $a\wedge b$)      \\
    \verb|\widehat{}|       &       ---        & $\widehat{\ }$ (e.g. $\widehat{abc}$) \\
\end{tabular}
\end{document}

If \Beam from marvosym is not satisfying, then you may try this solution.

\documentclass{article}
\newcommand{\textdirectcurrent}{%
  \settowidth{\dimen0}{$=$}%
  \vbox to .85ex {\offinterlineskip
    \hbox to \dimen0{\leaders\hrule\hfill}
    \vskip.35ex
    \hbox to \dimen0{%
      \leaders\hrule\hskip.2\dimen0\hfill
      \leaders\hrule\hskip.2\dimen0\hfill
      \leaders\hrule\hskip.2\dimen0
    }
    \vfill
  }%
}
\newcommand{\mathdirectcurrent}{\mathrel{\textdirectcurrent}}

\begin{document}
a =\textdirectcurrent{} b

$a \mathdirectcurrent b$

$a = b$
\end{document}

enter image description here

A maybe better implementation, that can work also in subscripts and superscripts, is

\newcommand{\mathdirectcurrent}{\mathrel{\mathpalette\mathdirectcurrentinner\relax}}
\newcommand{\mathdirectcurrentinner}[2]{%
  \settowidth{\dimen0}{$#1=$}%
  \vbox to .85ex {\offinterlineskip
    \hbox to \dimen0{\hss\leaders\hrule\hskip.85\dimen0\hss}
    \vskip.35ex
    \hbox to \dimen0{\hss
      \leaders\hrule\hskip.17\dimen0
      \hskip.17\dimen0
      \leaders\hrule\hskip.17\dimen0
      \hskip.17\dimen0
      \leaders\hrule\hskip.17\dimen0
    \hss}
    \vfill
  }%
}
\newcommand{\textdirectcurrent}{\mathdirectcurrentinner{\textstyle}{}}

However, the spacing parameters may need to be adapted to the main font used.

[Tex/LaTex] How to typeset the ground symbol ⏚ in LaTeX

One option is to define a command for this symbol taking it, for example, from the circuits.ee.IEC library (I wasn't sure if this symbol should be ord, rel, bin, so I opted for bin; also, there was no information about size or baseline position, but all these attributes can easily be adjusted):

\documentclass{article}
\usepackage{amsmath}
\usepackage{tikz}
\usetikzlibrary{circuits.ee.IEC}

\newcommand\Ground{%
\mathbin{\text{\begin{tikzpicture}[circuit ee IEC,yscale=0.6,xscale=0.5]
\draw (0,2ex) to (0,0) node[ground,rotate=-90,xshift=.65ex] {};
\end{tikzpicture}}}%
}

\begin{document}

$L\Ground {}$

\end{document}

enter image description here

Another option: this is listed as Unicode character 'EARTH GROUND' (U+23DA), so you could use XeLaTeX and a font supporting the symbol:

\documentclass{article}
\usepackage{fontspec}
\setmainfont{Symbola}

\begin{document}
The earth ground symbol $⏚$.
\end{document}

enter image description here

fileformat.info has a list of possible fonts supporting the symbol.
