Not that I am aware of. You might:

a. edit the Gmsh source code, particularly line 74 of Geo/MVertex.cpp
that reads

fprintf(fp, "%d %.16g %.16g %.16g ", _index, x() * scalingFactor,

b. edit the Calculix source code (good luck, it is Fortran!)

c. use another more modern option, say www.seamplex.com/fino

BTW, for the original developers, it would be nice to somehow being able
to change the hardcoded %.16g in runtime, for example to reduce the size
of the resulting ASCII mesh files.
