Hi all, Recently I've been working on a project that handles numbers composed of 16 32-bit (uint32_t) words. One of the requirements of the project is to be able to compare two such numbers to each other. To check if one number (a) is greater than or equal to another number (L), I wrote up the foll…

[image] blundt: I guess at this point I am just curious why it failed before. In other words, why reading a[16] and L[16] would cause if(i == 16) to fail. L has 16 elements, so an index i is only valid if 0 <= i < 16. Since you are reading L[i], the compiler is free to assume that the index i…
