[NTG-context] m-graph.mkiv format bug

There is a bug with format() as redefined in m-graph.mkiv 1e10 and 1e-10 truncate the tailing 0. (I have not been able to fix the code...) Alan Minimal example: \usemodule [graph] \starttext \startMPpage label(format("@g","1e-10"),(0, 0)) ; label(format("@g","1e+10"),(2cm, 0)) ; label(format("@g","1e-12"),(0, -.5cm)) ; label(format("@g","1e+12"),(2cm,-.5cm)) ; \stopMPpage \stoptext
