This is more of a tcl question then a VMD one, but here it goes:

to use the mathfunctions you have to specify the whole namespace.
so you have to write

*::tcl::mathfunc::round* *arg*

More info here: http://tmml.sourceforge.net/doc/tcl/mathfunc.html

If you use a lot of math functions you can also import the namespace and
just use round.
so after running
*namespace import **::tcl::mathfunc::**
*
*
just using round should work.
