Here is how my Sharp Compet 23 handles these situations: > What happens if I enter 12.999? Is that even possible?
You can enter 12.999, it will be displayed as 12.999 until you confirm. > If possible, what happens if I then press “+”? Does it round up and show 13.00 or does it show 12.99? There is no plus key on the calculator, since it uses RPN for addition and subtraction. Upon confirming with the equals keys, the value is truncated to 12.99. > For subsequent calculations, does it use the displayed value or the entered/calculated value with all decimal places? It uses the displayed value. Information about additional decimal places is lost. > How is a result like 1234567890.65 displayed? 34567890.65 and overflow? 1234567890 with no decimals? Something else? It displays 34567890.65, but with a lot of random decimal points and the overflow bulb being illuminated. Hope this helps, Oskar newxito schrieb am Freitag, 27.

I thought it would be easy, but a few questions have come up. Maybe someone who has such an old calculator can help. Let's assume that the calculator has a total of 10 Nixies and the fixed decimal places are set to 2. - What happens if I enter 12.999? Is that even possible? - If possible, what happens if I then press “+”? Does it round up and show 13.00 or does it show 12.99? - For subsequent calculations, does it use the displayed value or the entered/calculated value with all decimal places? - How is a result like 1234567890.65 displayed? 34567890.65 and overflow? 1234567890 with no decimals? Something else? Thanks Andy -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
