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 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 = 1.633124x10

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 by selecting the relevant command in the Edit menu, or use
the standard Macintosh keyboard shortcuts of 1-C, 1-X and 1-V
respectively. Cutting will copy the displayed value to the clipboard
and then set the display and operand to zero.
