What are the limits of Calculator?
Uses floating-point arithmetic and rounds display to 12 significant digits; this is not an arbitrary-precision financial calculator. Percentages on the right of +/− are relative to the left value (200 + 10% = 220). Other percentages divide by 100. Degree/radian mode affects trigonometry. History clears on navigation/reload.
