What are the maximum and minimum values of native numeric types?
A: Those actually depend on the architecure.The maxMin.cpp is a small program which prints the max and min values of every relevant C++ and CORBA numeric type. You'll need the maxMin.pro Qt-Project file, too. Compile it using this command line (make sure /alma/ACS-current points to the currently used ACS-X.Y version or check the .pro file and change it accordingly!): qmake make and attach the output here below if it is for an architecture not already listed.
