Actually, rather than focusing on the problem and the line of codes, i want to know about the difference between %ul and %lu I want to implement my own lu decomposition p,l,u = my_lu (a), so that given a matrix a, computes the lu decomposition with partial pivoting Maybe i could figure out what's wrong

Searching doesn't give me something useful (except that they are different)
Any explanation or link/reference is appreciated.
689 %lu is the correct format for unsigned long Sounds like there are other issues at play here, such as memory corruption or an uninitialized variable Perhaps show us a larger picture? 9 what is the difference between %zu and %lu in string formatting in c
%lu is used for unsigned long values and %zu is used for size_t values, but in practice, size_t is just an unsigned long Cppcheck complains about it, but both work for both types in my experience. I know there is a very similar question and answer on stackoverflow (here), but this seems to be distinctly different I am using statsmodels v 0.13.2, and i am using an arima model as opposed to a

Asked 11 years, 1 month ago modified 9 years, 11 months ago viewed 27k times When i print the number using the format specifier %llu, what is printed is %lu I also compare the value i get from atoll or strtoll with the expected value and it is smaller, which i guess shows that an overflow has occurred Why does an overflow occur if the number fits in a u64 variable
The number for example is 946688831000. /* c99 version */ printf(%lu\n, (unsigned long)sz) /* common c89 version */ if you don't get the format specifiers correct for the type you are passing, then printf will do the equivalent of reading too much or too little memory out of the array As long as you use explicit casts to match up types, it's portable.
