How to read a float from binary file in C?

Question

Everything I\'m finding via google is garbage... Note that I want the answer in C, however if you supplement your answer with a C++ solutio

Answer 1

How you have to read the floats from the file completely depends on how the values were saved there in the first place. One common way could be:

void writefloat(float v, FILE *f) {
  fwrite((void*)(&v), sizeof(v), 1, f);
}

float readfloat(FILE *f) {
  float v;
  fread((void*)(&v), sizeof(v), 1, f);
  return v;
}
