Sep 10, 2016 · More portable in comparison with some hardcoded values. Maybe uint32_t is not a great example. If you take std::numeric_limits<int32_t> for example, you do not have to make …

Apr 14, 2016 · In C99, I include stdint.h and that gives me UINT32_MAX as well as uint32_t data type. However, in C++ the UINT32_MAX gets defined out. I can define …

Sep 19, 2008 · Well, aside from jokes, if you're really looking for a useful memory rule, there is one that I always use for remembering big numbers.

Mar 4, 2011 · printf("%" PRIu32 "\n", UINT32_MAX); You can't just use %u because it isn't guaranteed that int is represented by at least 32 bits (it only needs to be represented by at …

When you use UINT32_MAX you are setting each of the 32 bits to 1 which is the maximum value 4 bytes of memory can represent. 1 is an integer literal which typically takes up 4 bytes of …

Feb 17, 2016 · @IanAbbott (replying to myself) - However, I think the type of the constant UINT32_MAX will always be one of unsigned int or unsigned long, rather than something …

Jul 28, 2015 · Is there any macro in C or C++ represent the max and min value of int32_t and int64_t? I know it can be literally defined by oneself, but it's better if there is a standard macro.

Sep 24, 2018 · I'm looking for a way to get (using Python) the maximum and minimum values of C types integers (ie uint8, int8, uint16, int16, uint32, int32, uint64, int64...) from Python.

Dec 18, 2020 · In -(UINT32_MAX), the negation is performed in the type uint32_t (and the parentheses have no effect). Negating within the uint32_t type wraps modulo 2 32 , so it …

I am working with code that uses types like uint8 (1 byte wide unsigned integer), uint16 (2 byte wide unsigned integer), uint32 (4 byte wide unsigned integer), etc..
