Whats the difference between %ul and %lu C format specifiers? But using %lu solved the issue Actually, rather than focusing on the problem and the line of codes, I want to know about the difference between %ul and %lu 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
printf - Difference between %zu and %lu in C - Stack Overflow 11 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 in statsmodels ARIMA model import numpy as np from statsmodels tsa arima model import ARIMA items = np log(og_items) items['count'] = items['count'] apply(lambda x: 0 if math isnan(x) or math isinf(x) else x) model = ARIMA(items, order=(14, 0, 7)) trained = model fit() items is a dataframe containing a date index and a single column, count I apply the lambda on the second line because some counts can be 0, resulting in
Why do I get %lu when I try to print a u64 variable with %llu . . . 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
c - Usage of zd vs lu for sizeof - Stack Overflow I understand that %zd is the suggested way to format the sizeof result However, I don't understand why that is necessary For example using lu gives me the same output, and isn't the result of siz
printf format specifiers for uint32_t and size_t - Stack Overflow size_t sz; printf("%zu\n", sz); * 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
c - Is it valid to use %lu in a format string for printf where PRIu32 . . . printf("%lu\n", i); I’d suppose yes, since I can see no reason why not However, if yes, then this would remove the need for existence of these macroified specifiers like PRIu32, so I figure I’d better ask The reason I’m asking it is that I’d like to create a format string for printf dynamically, and it’d be hard to allocate space for this format string if I don't know the size of
