Casio fx 991ms


On a fx-991MS? With many other models, including the fx-991ES, I'd say you have the calculator in binary mode but the 991MS doesn't have such a mode.

How to find inverse of log in a casio 991ms calci?


The inverse of the natural logarithm (in base e) is the EXPONENTIAL function (e^x). It shares the same physical key as the LN function. One is accessed directly and the other through the SHIFT key. The inverse of the logarithm in base 10 is the function 10^x. Both functions share the same physical key as described above.
More generally if y=log(in base b) of x =log_b(x) then x=b^(y). The base must of course be a non-zero positive number.

Hi, I have a Casio calculator fx-991MS giving me wrong answers!


Hello,
I am only looking for a plausible cause of the error, because I do not believe your calculator can make such a mistake. I think you accidentally activated the Exponential display format and did not pay attention to the small, raised -03 that came at the end of the number displayed. It is a common mistake for those not very familiar with Scientific or exponential notation.

Let us try to reset your calculator to the normal (floating point) format.
Press the [MODE] key a number of times until you reach a screen that has FIX, SCI, NORM and under each one a number (FIX 1, SCI 2), Norm 3). To have the number of decimal place you gave in your result (4 decimal digits), you press 1 to select Fix then 4.

Be aware that scientific calculators usually stop displaying results in floating point format ( 0.0000045 ) if the number is smaller then 0.001. So basically, 0.00099 will be displayed as 9.90-04, -04 being raised above the level, and in smaller size.

Hope it helps.
