This question already has an answer here: How to check programmatically whether a managed assembly is x86, x64 or AnyCPU? 2 answers Can I get the processor architecture by loading the dll programmatically in c#? Is there a class that can do this? I need to get wether the dll is x86, x64, MSIL etc.. Mike Ohlsen Assuming you are only looking at .net assemblies, you can use CorFlags.exe for look at the header of the image. This blog post explains the usage to determing how to read the results. Excerpt: Usage: Corflags.exe Assembly [options] If no options are specified, the flags for the given

This question already has answers here : Closed 8 years ago . Possible Duplicate: Performance of built-in types : char vs short vs int vs. float vs. double Hi. Assume, that you have 32-bit processor. Are 8-bit char and 16-bit short int types slower than native 32-bit int ? What about using 64-bit long long int ? Are this datatypes supported by hardware by default, or they are all transformed into 32-bit data anyway, by using additional instructions? In case, that I have to store a small amount of chars, isn't it faster to store them as ints? On any modern, practical machine, char , int , and

As far as I understood it, BigInts are usually implemented in most programming languages as arrays containing digits, where, eg.: when adding two of them, each digit is added one after another like we know it from school, e.g.: 246 816 * * ---- 1062 Where * marks that there was an overflow. I learned it this way at school and all BigInt adding functions I've implemented work similar to the example above. So we all know that our processors can only natively manage ints from 0 to 2^32 / 2^64 . That means that most scripting languages in order to be high-level and offer arithmetics with big

How do I find out if my processor is 32 bit or 64 bit (in your language of choice)? I want to know this for both Intel and AMD processors. plinth Windows, C/C++: #include <windows.h> SYSTEM_INFO sysInfo, *lpInfo; lpInfo = &sysInfo; ::GetSystemInfo(lpInfo); switch (lpInfo->wProcessorArchitecture) { case PROCESSOR_ARCHITECTURE_AMD64: case PROCESSOR_ARCHITECTURE_IA64: // 64 bit break; case PROCESSOR_ARCHITECTURE_INTEL: // 32 bit break; case PROCESSOR_ARCHITECTURE_UNKNOWN: default: // something else break; } Matt Howells C#, OS agnostic sizeof(IntPtr) == 4 ? "32-bit" : "64-bit" This is somewhat
