  • How does rand() work in C? - Stack Overflow
    Like rand(), rand_r() returns a pseudo-random integer in the range [0, RAND_MAX] The seedp argument is a pointer to an unsigned int that is used to store state between calls If rand_r() is called with the same initial value for the integer pointed to by seedp, and that value is not modified between calls, then the same pseudo-random sequence
  • How to generate a random int in C? - Stack Overflow
    If we use more than 53 bits, we get rounding bias Some programmers write code like rand() (double)RAND_MAX, but rand() might return only 31 bits, or only 15 bits in Windows OpenSSL's RAND_bytes() seeds itself, perhaps by reading dev urandom in Linux
  • Generate a value between 0. 0 and 1. 0 using rand () - Stack Overflow
    No, because RAND_MAX is typically expanded to MAX_INT So adding one (apparently) puts it at MIN_INT (although it should be undefined behavior as I'm told), hence the reversal of sign To get what you want you will need to move the +1 outside the computation: r = ((double) rand() (RAND_MAX)) + 1;
  • Whats the Right Way to use the rand () Function in C++?
    int randint() { int random = rand(); return random; } int main() { To get a unique sequence the random number generator should only be seeded once during the life of the application As long as you don't try and start the application mulitple times a second you can use time() to get a ever changing seed point that only repeats every
  • How do I get a specific range of numbers from rand ()?
    Related: How to generate a random int in C? Here is my answer there, which contains the definition for my int utils_rand(int min, int max) func, which returns a random number using rand() which is in the specific range from min to max, inclusive, thereby also answering this question
  • Should I use rand % N or rand () (RAND_MAX N + 1)?
    Unfortunately rand() (RAND_MAX N + 1) is also broken (in almost the same way), so the real answer is: don't use either of them The problem as outlined above is really fundamental, there is no way to evenly distribute X different values over Y results unless Y divides X
  • Differences between numpy. random. rand vs numpy. random. randn in Python . . .
    np random rand is for Uniform distribution (in the half-open interval [0 0, 1 0)) np random randn is for Standard Normal (aka Gaussian) distribution (mean 0 and variance 1) You can visually explore the differences between these two very easily:
