Change name for →Qπ - please suggest!

Anyone using exact would prefer to use QPI, as it's better functionality. Besides, you could give it an argument to keep the original functionality....or direct what to use (LN, SQRT, fraction, etc....maybe as a bitmap of flags).
I recommend in Home mode, using QPI, but calling it EXACT and in CAS mode using qpif, calling it exact (look at the original QPI thread).
