June 21, 2024printf unsigned long long as hex
Hi, printf's format specifier %X only prints values of up to 8 hex digits. I am using GCC on Gentoo Linux. (How do I find which GCC version I have?) Is it possible to print values as hex up to 15 or 16 hex digits? If not, a workaround would be appreciated also. TIA More on thecodingforums.com

July 2, 2007Why is unsigned long long int behaving as int?
%u means: print an unsigned integer. Only an unsigned integer will be consumed from the input to printf. This is disjoint from what is actually going on within i. So: all modern compilers should give you a warning here; and check out %llu. More on reddit.com

r/C_Programming on Reddit: Why is unsigned long long int behaving as int?
November 16, 2023 -
For the purpose of the code, the thing I wanna understand is why it goes like this:
include <limits.h>
…
unsigned long long int i;
…
for (i = 1; i < ULLONG_MAX / 10; i *= 10) {
printf(“%u\n”, i);
}
…
This thing prints:
1
10
100
1000
10000
100000
1000000
10000000
100000000
1000000000
1410065408
1215752192
3567587328
It looks like it’s overflowing around 10 billions, so I wonder if it somehow casted it as a normal int instead of an unsigned long long int. In the code I need it to multiply for an ever increasing number, until I hit the ceiling being ULLONG_MAX, but I don’t know why it behaves like this; something’s wrong with my rig? I’m running this code on a virtual box with Linux, my rig is 64 bit.
Any help is appreciated

Should it be printf(“%llu\n”, i);?

Answer (1 of 6): %lu is the standard order for unsigned long int. Just ran this snippet and it works for me. #include int main(void) { int unsigned long number = 600851475143LU; printf( "%lu", number ); return 0; } Let me know if you face some issue with this Vineeta Karki.

printf(), double and unsigned long int support - NXP Community
June 28, 2019 - where i is declared as uint64_t cast as an unsigned long int equal to 0x100000001 displays as "i = lu". If instead I select Newlib (nohost) in the Library/Header category, the second printf() call shown above will render the expected value, however when the first printf() shown is encountered the hard fault handler is inevitably invoked.

Format Specifiers in C — Complete List with Code Examples (2026)
May 19, 2026 - The %lu format specifier is used to print unsigned long integers in C. An unsigned long integer is a non-negative integer that typically occupies more memory than a standard unsigned int, allowing it to represent a larger range of values.

Conversion Specifier for Printing long in C with printf
For printing a long integer, you use the %ld specifier. This specifier tells printf to format the corresponding argument as a long int. For unsigned long values, use %lu.

This has nothing to do with MSP430. The printf implementation is a plain compiler-specific thing. A different compiler (and there are at tlest three I know of) may handle it differently. Even the support for different levels of printf support is not MSP specific.
