Need help_ Example or application of simple function

I'm studying Measurable Theory and my teacher asked us to find an example or application of simple function in real life, but I can't find one

step/floor function. I'll let you determine how/where these appear in "real life" (as if math class isn't real!)

Thank u very much, why didn't I think about step/floor function before >_<. Math class is real but I can't find and example of simple function in it (maybe because I don't understand the definition very well )

Sorry to be "that guy", but the wikipedia page can be somewhat helpful. The fact that a simple function can only take on finitely many values makes me think of the amount of money in a bank account.

I've think of the function that uses to calculate the distance from A to B, which is not a straight line, but unfortunately, my prof have forgotten about this so I've studied the next subject . But thank u anyway
