I have an 8-character string representing a hexadecimal number and I need to convert it to an int.This conversion has to preserve the bit pattern for strings \"80000000\" and higher, i.e., those numbe
Do you know any way to ef开发者_StackOverflow中文版ficient check if overflow/underflow occurs on x86 left shift arithmetically?A good option is to perform an arithmetic shift right after the shift lef
This question is probably stupid or paranoidal, but anyway :-). Given following code: DWORD hiRes; // will overflow about once in an hour
This quicksort is supposed to sort \"v[left]...v[right] into increasing order\"; copied (without comments) from The C Programming Language by K&R (Second Edition):
What do arithmetic underflow and overflow mea开发者_如何转开发n in C programming?Overflow From http://en.wikipedia.org/wiki/Arithmetic_overflow:
I had a bug that caused an integer overflow, resulting in wrong (negative) timestamps being written to the database. The code is fixed already, but I want to fix the wrong data, too.
I\'m working on a verification-tool for some VHDL-Code in MATLAB/Octave. Therefore I need data types whi开发者_StackOverflow中文版ch generate \"real\" overflows:
For a clever and complicated reason that I don\'t really want to explain (because it involves making a timer in an extremely ugly and hacky way), I wrote some C# code sort of like this:
I was writing a program in C++ to find all solutions of ab = c, where a, b and c together use all the digits 0-9 exactly once. The program looped over values of a and b, and it ran a digit-counting ro
To my shock, it turns out that the following code will compile without even warnings: public void test()
