What algorithm is used by computers to calculate logarithms?
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...

education - In which branch of mathematics does "logarithm" …
should I classify logarithm into arithmetic or algebra? Here is the definition of arithmetic by Oxford dictionary: the branch of mathematics dealing with the properties and manipulation of numbers. and the definition of algebra:
What is the point of logarithms? How are they used?
Logarithms are a convenient way to express large numbers. (The base-10 logarithm of a number is roughly the number of digits in that number, for example.) Slide rules work because adding and subtracting logarithms is equivalent to multiplication and division. (This benefit is slightly less important today.) Lots of things "decay logarithmically".
terminology - Where did the word "logarithm" come from?
logarithm: 1610s, Mod.L. logarithmus, coined by Scottish mathematician John Napier (1550-1617), lit. "ratio-number," from Gk. logos "proportion, ratio, word" algorithm: was derived from the name of 8th century Persian mathematcian al-Kwarizmi. Note: I think it's unusual for a term to derive from a person's name, especially in mathematics.
What are the parts of a logarithm called? [duplicate]
2016年12月27日 · $\begingroup$ I had "the logarithm of a number is the index to which the base is raised to equal that number" drilled into me 60 years ago. It's still helpful when I need a reminder what does what. It's still helpful when I need a reminder what does what.
Is there a term for the process of "taking a logarithm"?
"Logarithming" sounds like some sort of bad competition where you carve wooden logs or something, but everyone somewhat mathematically inclined would most likely understand that you mean "taking the logarithm" with this. On that note; what I always use myself is what you said yourself, namely "taking the logarithm" or "taking the log of".
logarithms - Approximating Logs and Antilogs by hand
Now, all of these need an unbelievable amount of time to build a table of logarithms, even if you want only logs of numbers from $100$ to $1000$ to four decimals. And there is no simple way to compute just one logarithm only by hand. There are the series above, polynomial approximations, and probably other ways, but nothing as easy to use as a ...
logarithms - Is there an approximation to the natural log function …
The logarithm does not. Suppose the power of the numerator and denominator are equal. Then for large values of x the rational function approaches a constant. The logarithm does not. And if the power of the numerator is greater, the rational function grows at …
