    This is something my wife just had to learn to accept. I’ll find something cool and realize I don’t want to go through life not understanding this topic. Most recently: floating point emulation.

        I’m particularly interested in how emulators deal with the mismatch between the FPU of the target hardware versus the host.

        It’s a fascinating and frustrating topic when you’re trying to emulate floating point in a specific way using hardware that doesn’t exactly do what you need. But almost. For example, maybe your host rounds differently or uses different status flags so the challenge is to find as many cases as possible where you can still exploit your host FPU without generating incorrect results.
