Algeabraic operation with #calc
 
Hi

== 1 ==
#calc, used in blockMeshDict context, seems to give different answers for the following:

== 2 ==

b 4;
c 3;
d 10;

// First one-line calculation
a #calc "b / d * c";

// Second one-line calculation
a #calc "(b * c) / d";

== 3 ==
I could not find any reasoning behind the difference; therefore, I thought it would be better to consider it as a small bug.

You don't include the answers you get in your post, which would help debugging a lot. I'm guessing integer division is to blame.

You could try to define b, c and d as scalars:

Code:
b 4.0;
c 3.0;
d 10.0;
and follow up with a detailed description of the input files and the error if it does not solve your problem.
