Actually, rather than focusing on the problem and the line of codes, i want to know about the difference between %ul and %lu The printf function takes an argument type, such as %d or %i for a signed int Maybe i could figure out what's wrong
Lu Caicedo Valdez
Searching doesn't give me something useful (except that they are different)
Any explanation or link/reference is appreciated.
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.

Lu decomposition error using sarimax in statsmodels asked 5 years, 4 months ago modified 3 years, 6 months ago viewed 4k times 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 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. 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 But i only know how to do it without pivoting.
