Math symbol for inexact differential

Math symbol for inexact differential

[w n]

[-- Attachment #1.1: Type: text/plain, Size: 266 bytes --]

Working on some thermodynamics and I need a math symbol for
an inexact differential, it is the letter d with a bar across.
Tried the following but failed

\starttext
\def\dbar{{\mathchar'26\mkern-12mu d}}
\startformula
d u = \dbar q + \dbar w
\stopformula
\stoptext

Normally one is using a lowercase delta according to:

True, I should not have used the term inexact differential.
How can I get a math symbol with a "d" and a bar across ?

How about  đ ? (U+00111)

That is a character in Latin Extended-A, so most text fonts
will have it (these days).

@Taco,

Can you give an example on how to use đ  (U+00111) in  \def\dbar{ ... }

Ideally I want to do
\startformula
d u = \dbar q + \dbar w
\stopformula

Like this?

\def\dbar{\mathop{\text{\it đ}}}

I do not know whether you want it to be \mathop or \mathord
