[Tex/LaTex] Better way to produce V\llap{–}


Is there a better way to get the symbol produced by V\llap{--}? I need it in math mode. The symbol is someitmes used to represent volume. The above hack is not the right symbol but something close.

A better implementation, where the dash is built as above, but over a phantom V; the real one is added later, so subscripts and superscripts are placed with respect to it.


    \ooalign{\hfil\hphantom{$\m@th V$}\hfil\cr\kern0.08em--\hfil\cr}%
