= Mantisse Expo
1.2&+12 indicates that the result is equivalent to 1.2x 10". This means that you should
move the decimal point in 1.2 twelve places to the right, since the exponent is positive.
This results in the value 1,200,000,000,000.
Mantissa Exponent
1.2£-03 indicates that the result is equivalent to 1.2x 10-3, This means that you should
move the decimal point in 1.2 three places to the left, since the exponent is negative. t
This results in the value 0.0012.
@Calculation Execution Display
When the calculator is busy drawing a graph or executing a long, complex calculation
or program, a black box (Mf) flashes in the upper right corner of the display. This black
box indicates that the calculator is performing an internal operation.
MWhen Errors Keep Occurring...
If you find that errors keep occurring when you try to perform an operation, use the fo!-
lowing procedure. to bring the calculator back to its initial settings and try again.
1. Use the Main Menu to enter the COMP Mode.
2. Press [Fa)(SET) or Gif]e) to switch to the set up edit display, and then press OF
(Deg) to specify degrees.
3. Press @[F3)(Nrm)&@ to enter the Norm 1 Mode.
