AI Thread Summary
Computers utilize algorithms to find logarithm values, often employing binary search methods for efficiency. The discussion highlights a resource that provides Python code for logarithm functions, indicating that such implementations can be found in libraries like math.h. It notes that most floating-point operations are processed by the CPU, but some legacy code may remain from earlier computing systems. The conversation emphasizes the evolution of computational methods for logarithms, reflecting on historical practices. Understanding these algorithms is essential for optimizing mathematical computations in programming.

How do computers find log values, is there some sort of algorithm to find it or do they just use binary search?

I found this by Google which seemed interesting:

You might be able to find the code in the math.h source code. Most floating point operations are going to go through the processor, but there's probably some legacy junk in there that gets left out at compile time for computers that existed before coprocessors became common.
 
Ok thanks.
 
Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
Thread 'Imaginary Pythagorus'
I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
