If you enter \((\sqrt{2})^21\) followed by EXE the FX4000P returns \(1\times10^{11}\), which shows that \((\sqrt{2})^2\) is being correctly evaluated as \(1.999\,999\,999\,99\) to 12 significant figures. However, entering \((\sqrt{2})^2\) followed by EXE returns 2 exactly, because of the rounding to 10 significant figures that happens when EXE is pressed. (Interestingly, the TI68 calculator allows the user to choose whether pressing ENTER rounds to 10 digits, or whether the full 13digit precision is retained.) Nigel (UK)
