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 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
c++ - printf and %llu vs %lu on OS X - Stack Overflow Possible Duplicate: how to printf uint64_t? Why is it that on my 64-bit Mac (I am using Clang) the uint64_t type is unsigned long long while on 64-bit Ubuntu the uint64_t type is unsigned long?
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

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
What exactly is GUID? Why and where I should use it? GUID technically stands for globally unique identifier What it is, actually, is a 128 bit structure that is unlikely to ever repeat or create a collision If you do the maths, the domain of values is in the undecillions Use guids when you have multiple independent systems or clients generating ID's that need to be unique For example, if I have 5 client apps creating and inserting
Difference between numpy. linalg. solve and numpy. linalg. lu_solve Indeed you are right: chaining scipy's scipy linalg lu_factor() and scipy linalg lu_solve() is perfectly equivalent to numpy's numpy linalg solve() Nevertheless, having access to the LU decomposition is a great advantage in practical situations First, let's proove the equivalence numpy linalg solve() states that: The solutions are computed using LAPACK routine _gesv Indeed, the github
