SOURCE: I need to find the antilog to -6.80 on a casioi fx-300ms calculat

Alot of people have this doubt, so I might as well make it clear.

Press the 10^x button (while pressing SHIFT, of course; it's exactly above the LOG button) followed by the number whose antilog you desire.

Example :
Let's say we need antilog(-6.8),
1. Press SHIFT, followed by LOG (i.e 10^x); this'll display a 10 on the screen;
2. Type in -6.8;
3. Press "=";
4. This'll display 1.584893192x10^-7 as the solution, which is correct!
5. Bye, lol :P

:-)

SOURCE: mode change

Hello,
Just so that we know what we are talking about. The natural display is the display mode in which fractions appear on two lines, radicals appear as radicals, log can be calculated in any base, etc. If that is what you understand by Natural Display, we are in agreement.
To set this mode, you turn calculator ON and press [SHIFT][MODE] (setup). The option is called MathIO, and it has the number 1.
Thus [SHIFT][MODE][1:MathIO].
Hope it helps.

SOURCE: How do i calculate antilog

For common logs (logs in base 10) use the 10^x function : Press [SHIFT] [Log] to access it.
For natural logs, use the exponential function. Press [SHIFT][ln] to access it.

SOURCE: Casio fx-991ES, how to calculate

At a blank screen, enter your IRR formula in terms of the variables using ALPHA and ')' for variable X. For example: -1000 200/((1 X)^1) 200/((1 X)^2) ... rest of subsequent years. Then, press CALC. It will prompt you to enter values of your variable (X in this example). Don't worry if there's already a value displayed - this is just the most recent value that has been stored as that letter. Simply enter your value (in terms of your IRR guess) and then press [=]. You will have to repeat this for each IRR guess until you reach almost ZERO.

Find antilog on es991


The natural logarithm function, denoted ln(x) has an inverse function called the exponential function, denoted e^x. That is what you call the antilog (I prefer the euphony of the exponential).
On calculators the two functions share the same physical key: One function is accessed directly and the other indirectly (SHIFT, 2nd F, or 2nd)
On the Casio FX-991ES the function ln and e key is the the one above the tan key.

The common logarithm or logarithm in base 10, denoted log(x) has an inverse function, the power function in base 10 or 10^x. In your terminology this would also be an antilogarithm.
The common log is accessed by pressing the log key to the left of the ln key, and the 10^x function is obtained with the sequence [SHIFT][log]

Use the shifted function of the appropriate log key (log for common (base 10) log/antilog and ln for natural (base e) log/antilog). For example, to calculate the common antilog of 2, press SHIFT log 2 = and to calculate the natural antilog of 2, press SHIFT ln 2 =.

How to find antilog on casio fx-991MS?


For common antilog, use 10^x, the shifted function of the log key. For natural antilog, use e^x, the shifted function of the ln key. In either case, press the appropriate function and then enter the expression whose antilog you're seeking.
