adjustscale()

void datrw::su::ScalCoo::adjustscale

(

)

adjust scale to optimal representation of significant digits

This function removes trailing zeroes from the ScalCoo::coo value, by chosing an appropriate scale value. Upon return from this function the scale power is as large as possible. Any increase in the power of the scale value will result in truncation of the coordinate value.
