First and foremost, let me say that I just starting using this library yesterday, so my understanding of it is still fairly basic. I'm trying to capture the FPS of a vision processing program I'm creating and output it to a screen using the chrono library. In my case, I need to cast the elapsed time taken after I start a steady_clock to a double (or some other numerical typedef I could treat like a double). I looked through reference documentation and tried working with the duration_cast and time_point_cast functions, but neither of those seem to be what I'm looking for.
My question is; is there any way to simply cast the numerical value of a clock's current state in seconds to a primitive data type?
Any help would be appreciated.
