Casio FX-260 Calculator - Answered Questions & Fixed issues
How do I enter -log(3.45x10^-11)?
I would do it the very old fashion way, but I know it will work on any calculator;)
3.45 x 10 x/y (x to the power of y) (11+/-) /* this should get you the number inside the bracket */
log /* this should give you the log of the bracket */
*1 +/- = /* this should give you the answer*/
I get 10.462180904926725879050933879218.
Good luck.

Changing decimals to fractions
You can always convert a fraction to a decimal. The reverse may not
always be possible. Look at the example on the screen capture.
You
may be lucky and recover a fraction you have just converted into
decimal format, but you cannot just write 0.333333333333 and expect the
calculator to convert it to 1/3: The true fraction 1/3 has an infinite
number of 3's after the
decimal mark.

Remove decimal dot
Why? If number is decimal the dot is needed. If the result is an integer, just ignore the dot.

How to solve for future value
If you have the formula you can use the calculator to find future values. But do not count on this calculator to do it for you. It does not have a business/finance application.

Deg won't to comp,etc.
As a first time user, the only way to start is to read (at least skim) through the user's guide. If you have no time for that and you need assistance with a particular question take the time to formulate it in an understandable manner. It would have been my pleasure to help you, if only I understood what you wanted. Please try again.

How do I change from
You can set your display mode to FIX or NORMAL ( 1 or 2) if you have them. However if the result is too small ( less then 0.001) or too large the calculator will use the scientific format. Generally if there are not enough display positions to show your result, the calculator uses scientific notation.
