I have a binary file of doubles that I need to load using C++. However, my problem is that it was written in big-endian format but the fstream >> operator will then read the number wrong because my machine is little-endian. It seems like a simple problem to resolve for integers, but for doubles and floats the solutions I have found won't work. How can I (or should I) fix this?

I read this as a reference for integer byte swapping:
