Performance is tricky. Especially, if you are working with very fast operations. In today benchmarking exercise, we will try to measure performance of two simple methods which calculate minimum of two numbers. Sounds easy? Ok, let's do it, here are our guinea pigs for today:
I've been coding with .NET for a long time. In all of that time, I haven't really had a need to figure out the nitty-gritty differences between float and double, or between decimal and pretty much any other type. I've just used them as I see fit, and hope that's how they were meant to be used.
Extending this question: How an object knows what type it is? Is it the compiler or the runtime that knows that? How this is related to the CLR? As C# is statically and strongly typed, maybe the method call GetType() does not really exist, and the compiler can replace it with the appropriate result already at compile time?
According to the NASA ‘Near Earth Object Program’ asteroid ‘101955 Bennu (1999 RQ36)’ has a Cumulative Impact Probability of 3.7e-04, i.e. there is a 1 in 2,7000 (0.0370%) chance of Earth impact, but more reassuringly there is a 99.9630% chance the asteroid will miss the Earth completely!
