Hi Ryan, By default the HP50g displays in scientific notation, but you can modify this behavior changing the "Number Format" option in MODE setup to Fix (fixed) and choose, lets say, 9 decimal digits. You'll see the result as you want. But in this configuration all numbers will be shown with 9 decimal digits. Regards. (read...)
