Casio fx-991W Calculator User Manual


 
E-9
•You cannot set the angle unit or the display mode while
the calculator is in the BASE-N mode.
The COMP, CMPLX, SD, and REG modes can be used
in combination with the angle unit modes.
•Be sure to check the current calculation mode (SD, REG,
COMP, CMPLX) and angle unit mode (DEG, RAD, GRA)
before beginning a calculation.
k Input Capacity
The memory area used for calculation input can hold 79
“steps.” Whenever you input the 73rd step of any calcu-
lation, the cursor changes from “_” to “k” to let you know
memory is running low. If you still need to input more,
you should divide your calculation into two or more parts.
k Making Corrections During Input
•Use e and r to move the cursor to the location you
want.
•Press
[ to delete the number or function at the current
cursor position.
•Press
A K to change to an insert cursor t. Inputting
something while the insert cursor is on the display in-
serts the input at the insert cursor position.
•Press
e, r, A K, or = returns to the normal cur-
sor from the insert cursor.
k Replay Function
•Pressing r or e recalls the last calculation you per-
formed. You can then make any changes you want in
the calculation and re-execute it.
•Pressing
t does not clear Replay memory, so you can
recall the last calculation even after you press
t.
•Replay memory is cleared whenever you start a new
calculation, change to another mode, or turn off power.
