Multiplication with dimexpr?

Question

Hey everyone, is there a way to do this with a multiplication instead of two additions?

\dimexpr\linewidth+\lst@linebgrdsep+\lst@linebgrdsep\relax

Thank you in advance :)

If \lst@linebgrdsep is a register then:

\dimexpr\linewidth + 2\lst@linebgrdsep \relax

Hint: Real numbers are also possible.

Otherwise:

\dimexpr\linewidth + (\lst@linebgrdsep)*2 \relax

Note, the first factor is the length value, the integer factors follows afterwards in the product. This is limited to integer numbers.

Real numbers can be supported by wrapping the macro \lst@linebgrdsep in \dimexpr.

\dimexpr\linewidth + 1.5\dimexpr\lst@linebgrdsep\relax \relax

I don't know the definition of \lst@linebgrdsep, so I define it here.

\newdimen\lst@linebgrdsep
\lst@linebgrdsep.5\textwidth
\edef\x{\the\dimexpr\linewidth+\lst@linebgrdsep*2\relax}
\show\x
