root of a quadratic equation
These two equations help to solve a root of a quadratic equation:
<< 2 >LIST SWAP / EVAL SWAP 2 / DUP SQ ROT  v/ DUP2 + ROT ROT  >> << 3 PICK / SWAP ROT 2 * / DUP SQ ROT  SQRT DUP2 * ROT ROT  >> [quote='tigger' pid='40913' dateline='1440236517'] << 2 >LIST SWAP / EVAL SWAP 2 / DUP SQ ROT  v/ DUP2 + ROT ROT  >> The calculator put a blank between the  and the 2 automatically. This could have been the mistake in the program. << 2 >LIST SWAP / EVAL SWAP  2 / DUP SQ ROT  v/ DUP2 + ROT ROT  >> << 3 PICK / SWAP ROT 2 * / DUP SQ ROT  SQRT DUP2 * ROT ROT  >> Is there a sign for SQRT on this page? When I punched the keys in the calculator itself made a blank between the  and the 2. How could I know that the calculator made this mistake? Does the HP always makes mistakes like this? How can I avoid this kind of mistakes? There might be any hope and help to rectify these short programs?
