WebMay 27, 2014 · If you want a closer mapping, you need to use smaller precision NUMBER fields in Oracle. I use: NUMBER (9) => Int32 NUMBER (18) => Int64 NUMBER (19+) => Decimal in the data access code generators that I've written. ORMs may do the same, or not. Typically NUMBER (18) is adequate for any integer keys you will ever need. 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.

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.
