To obtain further functions press and hold the option key. In general, the function obtained is the inverse of the normal one eg sin becomes arcsine, log natural (ln) becomes e x, square root becomes x 2.
The M+ key becomes the M- key, subtracting the displayed value from the memory, and MR becomes CM, clearing the memory.
The C key becomes CE, which will clear the last entry, but not totally clear the calculator.
The two keys that have new functions are the % which becomes
¹(pi), and +/- which becomes 1Úx.
The last two keys are the yth root of x and (with option key down) x y (x to the power y). To use these keys enter the x value first, then press the key. You will be prompted to enter the y root or power, and when youÕve done so, press equals to get the result. Unlike many calculators, iMalc lets you correctly determine odd number integer roots of negative numbers.
The Display
The display will show up to 12 digits (including a minus if present).
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.
You can copy, cut and paste to and from the display window using either the Edit menu, or use the standard Macintosh keyboard shortcuts of
