The display will show up to 12 digits (including a minus if present). Numbers in exponential form will be shown with an e followed by a plus or a minus and then exponent. eg 1.633124e+16 = 1.633124x1016
Also in the display, on the left hand side are two indicators. The one on the bottom left is the degree/radian/grad indicator and shows which mode the calculator is in, displaying a D, R or G respectively. This is always lit.
Initially unlit is the memory light, M, above the trig mode indicator. If there is a number stored in memory other than zero then this indicator will be lit.
To change the trig mode, just click on or near the indicator light. It will cycle through D,R and G.
