# Usage of the \dimexpr command

I have MiKTeX 2.3 and its version of e-TeX does not support \dimexpr command. I do not want to update this MiKTeX now and wonder, is it possible to define the \dimexpr command, probably with use of calc package?

• e-TeX included \dimexpr from the start, so if you have e-TeX you should have \dimexpr. Have you tried running for example elatex rather than latex to ensure the extensions are enabled (used to be necessary)? – Joseph Wright Nov 10 '13 at 8:25
• Great thank! elatex.exe and pdfelatex.exe does my job. The only question. Usual – user40791 Nov 10 '13 at 9:28
