I’m using the API mpmath to compute the following sum Let us consider the serie u0, u1, u2 defined by: u0 = 3/2 = 1,5 u1 = 5/3 = 1,6666666… un+1 = 2003 - 6002/un + 4000/un un-1 The serie conv...

I have to find log of very large number. I do this in C++ I have already made a function of multiplication, addition, subtraction, division, but there were problems with the logarithm. I do not n...

As a personal project I am working on implementing an Arbitrary Precision number type for a pet project of mine. I already know about all the popular, tested and robust libraries out there that do...

I have a numpy 2d array [medium/large sized - say 500x500]. I want to find the eigenvalues of the element-wise exponent of it. The problem is that some of the values are quite negative (-800,-1000,...

I recently came across the subject of exact real arithmetic after reading this paper and this paper. I have found a number of papers that discuss realizations of exact arithmetic using signed digi...

Oauth requires a random 64-bit, unsigned number encoded as an ASCII string in decimal format. Can you guys help me achieve this with php? Thanks

How the heck does Ruby do this? Does Jörg or anyone else know what's happening behind the scenes? Unfortunately I don't know C very well so bignum.c is of little help to me. I was just kind of cu...

I need to convert a large (too large for the built-in data types) hex string to a string with it's decimal representation. For example: std::string sHex = "07AA17C660F3DD1D2A1B48F1B746C148"; std::...

I need the fastest library that is available for C++. My platform will be x86 and x86-64 which supports floating points.

Possible Duplicate: what is the equivalent for java class : BigDecimal in c# I know in this post: Arbitrary precision decimals in C#? says to use java.math.BigDecimal, but I don't hav...

I'm writing a PHP library that has a Number class that uses the bcmath extension for arbitrary precision. I have two questions: How much slower is bcmath compared to using the built-in int and flo...

Is there any standard way to use integers of arbitrary length in Perl? I am working on code that generates x64 assembly for tests, and I'm tired of manipulating 32 bits at a time. I'm using Perl 5...

Is there a pure python implementation of fractions.Fraction that supports longs as numerator and denominator? Unfortunately, exponentiation appears to be coded in to return a float (ack!!!), which ...

I'm using long double in a C program to compute 2D images of the Mandelbrot Set but wish to have further precision to zoom deeper. Are there any performance gains to be had from an arbitrary...
