There is an x86 assembly instruction ADC. I\'ve found this means "Add with carry". What does this mean/do? How would one implement the behavior of this instruction in C++?
I\'m attempting to use LAST_INSERT_ID on an auto incremented index that has moved past the signed int value 2147483647. This column is an unsigned int. However, LAST_INSERT_ID() is returning an invali
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 have two tables with 10-20 million rows that have GUID primary keys and at leat 12 tables related via foreign key.The base tables have 10-20 in开发者_Python百科dexes each.
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.
