Question about Casio FX-260 Calculator
I cannot get out of the DEG or RAD or GRA modes. I am trying to get back to COMP mode which should be indicated by an absence of display in the mode indicator. MODE 9 does nothing
Sorry, but I think you misunderstood what the manual says. See the not on the screen capture.
True the sentence is not very clear, but what it means is the following:
All modes (except COMP) will have an indicator (with the appropriate labeling) displayed. When in COMP mode the COMP indicator is not displayed.
The truth of the matter is that computation- wise you have two MODES only : the general COMPutational mode and the Standard Deviation (SD Statistics) MODE. These two are incompatible because the key layout is different.
But to compute trig functions
You can only remove DEG by changing the angle unit to RADians or GRADs. In so doing, the new unit indicator (RAD, GRAD) will be displayed instead. There is no point worrying about the angle unit indicator unless you are performing coordinate conversions or calculating trigonometric functions or the inverse trigonometric functions.
MODE 9 cancels the FIX display format: decimal are displayed with a fixed number of decimal places (set by the user). After this key sequence the decimal display format reverts to NORM(al).
