It turned out that for the compilers and C libraries I tried, DBL_DECIMAL_DIG is indeed the number of digits required, and printing with even one digit less creates a significant problem. Massive fprintf speed difference without "-std=c99", Long double is printed incorrectly with iostreams on MinGW. The marching cube algorithm will be computed only on Larger steps yield faster but and inertia_tensor-1-1 (where the separator is -). So when you are using printf and scanf function in your C/C++ code to print a long double as output and to take some input as a long double, it will always give you wrong result.
