ADJPREC _ _ _ _ _ _ _ _ _ _ _ _ switch
When a real number is input, it is normally truncated to the precision in effect at the time the number is read. If it is desired to keep the full precision of all numbers input, the switch adjprec (for <adjust precision>) can be turned on. While on, adjprec will automatically increase the precision, when necessary, to match that of any integer or real input, and a message printed to inform the user of the precision increase.
