Foam::functionEntries::calcEntry
Uses dynamic compilation to provide calculating functionality for entering dictionary entries.
E.g.
a 1.0;
b 3;
c #calc "$a/$b";
Note the explicit trailing 0 ('1.0') to force a to be read (and written) as a floating point number.
Internally this is just a wrapper around codeStream functionality - the #calc string gets used to construct a dictionary for codeStream.
