C# int64 vs int32

WebJan 25, 2013 · Where int8_t and int32_t each have a specified size, int can be any size >= 16 bits. At different times, both 16 bits and 32 bits have been reasonably common (and for a 64-bit implementation, it should probably be 64 bits). On the other hand, int is guaranteed to be present in every implementation of C, where int8_t and int32_t are not. WebOct 29, 2010 · The best way to fix this is to convert the aliases dictionary to use an Int64 type as well. It's always safe to convert an int to Int64 so there is no information loss in this conversion. Ideally you'd convert GetUrlAliasesByType to return an IDictionary. The rest of the system is now using Int64 so this conversion …

Operations on integers are exact. double is a floating point data type, and floating point operations are approximate whenever there's a fraction. double also takes up twice as much space as int in many implementations (e.g. most 32-bit systems) . Share. WebDec 16, 2009 · Sure is a difference - In C#, a long is a 64 bit signed integer, an int is a 32 bit signed integer, and that's the way it always will always be. So in C#, a long can hold an int, but an int cannot hold a long. C/C++ that question is platform dependent.
