Antilog of 250 - Casio FX-250HC Calculator

The antilog functions are the 2nd functions of the log functions on the top row of the keyboard.

To calculate the natural antilog of 3.1, press 3 . 1 2nd LN
To calculate the common antilog of 3.1, press 3 . 1 2nd LOG

Make sure you use the (-) key to enter negative values, not the - key. For example, to calculate the common antilog of -5, press
SHIFT log (-) 5 =

To calculate the natural antilog of -5, press
SHIFT ln (-) 5 =

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 =.

Do you mean the antilog? For the common antilog, use the shifted function of the LOG key (marked 10^x). For the natural antilog, use the shifted function of the LN key (marked e^x).

For example, to calculate the common antilog of 0.5, press . 5 SHIFT [10^x] = and get about 3.16. To calculate the natural antilog of 0.5, press . 5 SHIFT [e^x] = and get about 1.65.

Antilog is a somewhat outdated terminology for the inverse function of the logarithm.

To calculate on your FX-115ES the base 2 antilog of 4, key in

Correct result is 16.

The natural antilog function is the shifted function of the natural log key (ln). The common antilog function is the shifted function of the common log key (log).

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.

The antilog is the inverse of the logarithm. Not too surprisingly, it's invoked as the 2ND shift of the appropriate log key.

For the common antilog, use the 10^x key (2ND LOG). For example, 2ND LOG 3 ENTER gives 1000 as the common antilog of 3.

For the natural antilog, use the e^x key (2ND LN). For example, 2ND LN 3 ENTER gives 20.08553692 as the natural antilog of 3.

For common antilog: 2ND 10^x (-) 13.51 ) ENTER

For natural antilog: 2ND e^x (-) 13.51 ) ENTER
