Math & Science ⇒ Upright "d" in derivatives and integrals

[Singularity]

The "d" in integrals and derivatives is supposed to be an upright "d". But when you make it in an equation, it becomes italicized. I can't find a symbol anywhere which represents this "d" upright. Lately, I've been using this:

Code: Select all

\newcommand{\wrt}[1]{\mathrm{d}{#1}}

.
Is there a symbol for this that I'm missing? If not, does anyone have a better solution than mine? I'm kind of tired of this solution (it's a lot of typing for one character).
Thanks.

Using \mathrm is ok. If you would like to save typing, perhaps define \dx, \dy etc. with \mathrm.

The cool package defines \D to typeset derivatives. Its style can be customized:

Code: Select all

\documentclass{scrartcl}

\usepackage{cool}
\Style{DSymb={\mathrm d},DShorten=true,IntegrateDifferentialDSymb=\mathrm{d}}

\begin{document}

\[\D{f}{x}\]
\[\D{f}{x,y,z}\]
\[\Int{f(x)}{x,a,b}\]

\end{document}
