 Thank you for the quick reply.
 
 Is your solution cout.setf(ios_base::floatfield, ios_base::floatfield) equal
 to unsetf(ios_base::floatfield)? I am now using the latter, and it seems to
 do the same as setf(0, ios_base::floatfield) when using the Sun CC compiler.
 Btw, the setf(0, ios_base::floatfield) statement is taken from an example in
 The C++ Programming language by Bjarne Stroustrup.
 
 Yours, Jon Gjerde
