Per the user manuals, neither the fx-96SG PLUS for the fx-97SG X offer arbitrary-base logarithms. They only offer logarithm base 10 (log X) and logarithm base e (ln X). To compute an arbitrary logarithm base, you need to use the identity log_a(b) = log_c(b)/log_c(a) Where you can choose whichever base c happens to be available on your instrument. (On these calculators, the bases which are available are 10 and e.) For example, log2(4) = ln(4)/ln(2) = 2.0 Answer from goosnarrggh on reddit.com

How to log base 2 on a calculator - Quora
Answer (1 of 18): If the calculator doesn’t have a key for logarithms with arbitrary bases, you use the change-of-base identity. For example: log(base 2) of 1024 = log(1024) / log(2) The latter works for any base; you just need to make sure ...

April 4, 2018How do I calculate the logarithm in base 2?
To calculate the logarithm in base 2, you probably need a calculator. However, if you know the result of the natural logarithm or the base 10 logarithm of the same argument, you can follow these easy steps to find the result. For a number x:
-
Find the result of either
log10(x)orln(x). -
Divide the result of the previous step by the corresponding value between:
-
log10(2) = 0.30103; or -
ln(2) = 0.693147.
-
-
The result of the division is
log2(x).

What is the logarithm in base 2 of 256?
The logarithm in base 2 of 256 is 8. To find this result, consider the following formula:
2x = 256
The logarithm corresponds to the following equation:
log2(256) = x
In this case, we can check the powers of 2 to see if we can find the value of x: 20 = 1, 21 = 2, 22 = 4, …, 27 = 128, and 28 = 256.
Since we found the argument of our logarithm, we can write that:
log2(256) = 8.

Why is the logarithm in base 2 important?
In a computer world, binary code is of essential importance: words, numbers, pictures, and everything else can be reduced to a string of 0s and 1s. Since the binary code uses only two digits, the number 2 appears consistently in computer science.
The widespread appearance of log2 in computer science has no strong mathematical reason (since logarithms can change base by multiplication) but can be useful. For example, using log2 to compute entropy allows us to obtain the result expressed in bits, which are the natural unit.

They don't have a way to enter it directly, gotta use the relation loga(b) = logx(b) / logx(a) for any x, so if you want something like log2(15) you can enter it as log 15 / log 2 , or ln 15 / ln 2

r/calculators on Reddit: Looking for a calculator with log base-2 button
November 17, 2023 -
I currently own the Casio fx-82MS calculator, which almosy perfectly works for my needs in physics and information theory. I would rather do plots and complex calculations in the computer, so I reserve the calculator for quick stuff when using pen and paper.
However, this is where my problem begins: a lot of my quick-mathing involves taking log BASE-2. I've grown the habit of converting the base everytime log(n)/log(2), but really this is a hassle and breaks the immersion of whatever I'm trying to think.
So my question is: do you know of any low-end calculator (not high-end graphing calculator) with either a dedicated Log BASE-2 button or a Log BASE-Y button?
Alternatively, if there's a configuration or modification I can do to permanently turn my log button into log base-2, I'm open for that as well (I'll never need to log base-10, I swear).
