That might apply if columnvalue() hat been used in a numerical 
expression here.  But using it as the argument of gprintf() doesn't 
really satisfy such a condition.

I would probably try something like

	gprintf("%5.2e", 0.0+columnhead(5) )

That is actually using columnhead(5) in a numeric expression.
