  • 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
  • What are the parts of a logarithm called? [duplicate]
    $\begingroup$ 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
  • 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"
  • 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"
  • How is $\\ln$ pronounced by English speakers?
    It is unfortunate that secondary-school algebra textbooks teach students that "log" with no subscript always means the base-$10$ logarithm Since the natural logarithm is indeed the natural logarithm to use in calculus, it is written as $\log$ with no subscript Some mathematicians write it as $\ln$ but still understand $\log$ written by others
  • logarithms - Approximating Logs and Antilogs by hand - Mathematics . . .
    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
  • What is discrete logarithm? - Mathematics Stack Exchange
    Okay, now this is where the discrete comes in: the discrete Logarithm is essentially just the Logarithm over a finite group I'll explain what that means below; A group in Mathematics is just a set of objects that have a sort of "multiplication operation" associated with them - for example, the real numbers (technically without $0$ ) form a
  • Calculate logarithms by hand - Mathematics Stack Exchange
    I'm thinking of making a table of logarithms ranging from 100-999 with 5 significant digits By pen and paper that is I'm doing this old school What first came to mind was to use $\\log(ab) = \\lo
