I would like my C function to efficiently compute the high 64 bits of the product of two 64 bit signed ints.I know how to do this in x86-64 assembly, with imulq and pulling the result out of %rdx.But
How is the derivative of a f(x) typically calculated programmatically to ensure maximum accuracy? I am implementing the Newton-Raphson method, and开发者_StackOverflow中文版 it requires taking of the
I have a 1-dimensional float array of root mean square values, each calculated with the same window length. Let\'s say
I\'m trying to prove the statement ~(a->~b) => a in a开发者_运维知识库 Hilbert style system.Unfortunately it seems like it is impossible to come up with a general algorithm to find a proof, but I\'m l
I have to check, if given number is divisible by 7, which is usualy done just by doing something like n % 7 == 0, but the problem is, that given number can have up to 100000000, which doesn\'t fit eve
Ever since I needed to work with PI (3.1415...) in C# I have used Math.PI to get the value.Usually I would just use values like Math.PI/2.0 or 2.0*Math.PI, but now I have just noticed that XNA provide
For binary search tree type of data structu开发者_高级运维res, I see the Big O notation is typically noted as O(logn).With a lowercase \'l\' in log, does this imply log base e (n)as described by the n
I am trying to compute 2^1000 (2 to the power of 1000) using c#.I need the value to all places.I\'ve been scratching my head for a while now because I can\'t seem to figure out a way to achieve this i
I\'m working with graphing accelerometer data here, and I\'m trying to correct for gravity. To do this, I get the acceleration vector in spherical coordinates, decrease the radius by 1g, and convert b
I want to see the values of the function y(x) with different values of x, wher开发者_如何学Goe y(x) < 5:
