When I was looking the energy score printed in the make_pdb.cc file, I found there was code like
iunit << A( 15, "score:" ) << F( 11, 2, score ) << '\n';
What is the F()? Thank you!
It's a string formatter to control things like number of decimal digits and left/right justification. I don't know exactly what it does. It's probably in the ObjexxFCL libraries.
