Becaue *you* decide when to press the \(\sqrt{x}\) key. Pressing it immediately extracts the square root of what's in the X register. The DM42/HP-42S does not work with expressions like an RPL machine does. There are only 10 types of people in this world. Those who understand binary and those who don't. |
