I didn't know math had a "floor" function. The squared cosine was very cleaver!

Interestingly, floor would work converting into an integer? The guy in the video said math didn't have a way to convert to an integer....?

When did he say that?

3:48

He talks about "what if we don't have a standard programming language at our disposal?" and "using traditional mathematical functions instead". I took that as there is no way to convert a decimal into an integer with just a math symbol. However this is the first time I see a floor function as a math symbol!

The (cos(x * pi) * cos(x * pi)) is something I will remember and use myself when needed (for a whole number of x, you will get 1 from the squared cosine). Being able to manipulate sine curves is very important since a lot of analog stuff require such knowledge. So this video has helped me in a few ways! Thank you for finding it!
