I am trying to calculate 100! (that is, the factorial of 100). I am looking f开发者_JAVA百科or the simplest way to accomplish this using C. I have read around but have not found a concrete answer.
As some of you may notice this question is problem 16 from Project Euler. I have solved it using the new \"bigInt\" feature of C# 4.0 which was fairly straightforw开发者_C百科ard but which is also not
i am using php and running sql queries on a mysql server. in order to prevent sql开发者_运维问答 injections, i am using mysql_real_escape_string.
I want to store a C#.NET ulong into a T-SQL database. I d开发者_JAVA百科on\'t see any provisions for doing this, as the SQL bigint has the same Min/Max values as a normal long.
I am just trying to implement multi-precision arithmetic on native MIPS. Assume that one 64-bit integer is in register $12 and $13 and another is in registers $14 and $15.
I\'m building a small BigInt library in C++ for use in my programming language. The structure is like the following:
In C++, I have a bigint class that can hold an integer of arbitrary size. I\'d like to convert large float or double numbers to bigint.
I have a problem with the Java BigInteger class: I can\'t paste a large value into BigInteger. For example, let\'s say I want to assign a BigInteger to this number:
