I would like to know how logarithms are calculated by computers. The GNU C library, for example, uses a call to the fyl2x() assembler instruction, which means that logarithms are calculated directl...

You could build a table of certain logarithms: 10^ (-1/2), 10^ (-1/4), etc. Twenty such entries would allow you to calculate logs to 5 places by multiplying your target number by the appropriate power of ten …

Feb 14, 2016 · I would need to be able to compute logarithms without using a calculator, just on paper. The result should be a fraction so it is the most accurate. For example I have seen this in math class …

Aug 14, 2020 · As the title states, I need to be able to calculate logs (base $10$) on paper without a calculator. For example, how would I calculate $\\log(25)$?

Jul 5, 2020 · I want to calculate the logarithm of any base completely by hand. I don't want to use a calculator, tables or predefined numbers. The only mathematical functions available for the …

22 I have read through questions like Calculate logarithms by hand and and a section of the Feynman Lecture series which talks about calculation of logarithms. I have recognized neither of them useful …

Sep 6, 2023 · Logarithms aren't magic; there are specific algorithms for computation (i.e. compute up to whatever precision we want) that we could do by hand, or that a machine could do mechanically. …

Apr 23, 2017 · It is important to understand that the table of logarithms allows too the reverse computation that is to compute $10^ {\,x}$. Of course $10^ {\,\log (2)}=2$ so that for example $10^ …

Aug 6, 2018 · However, how would they calculate logarithmic problems? I couldn't really find any information about this and was hoping someone would point me in the right direction or provide any …

Oct 5, 2019 · According to Wikipedia, this is so fast and cheap to compute that this can be used to compute the exponential function using logarithms faster than series approximating the exponential …
