Detailed Description

ScopedFloatingPointEnv is used to easily enable Floating-point exceptions. The initial state is automatically restored when the object is deleted.

Note(user): For some reason, this causes an FPE exception to be triggered for unknown reasons when compiled in 32 bits. Because of this, we do not turn on FPE exception if x86_64 is not defined.

Todo

(user): Make it work on 32 bits.

(user): Make it work on msvc, currently calls to _controlfp crash.
