Way to declare float compile-time constant in C

Question

I know that I can declare a named compile-time constant in C for integers by using enums, but is there a way to declare named compile-time constants in C for floats as well, without using macros (I know that C++ has constexpr, but I am strictly using C right now)? Answers containing compiler-specific C-language extensions are also greatly appreciated.

Answer 1

Use array of const float. Which will produce constant data of type float. const float *arr[3] = {11.21,21.31,31.23}
