I'm not sure if this can be done without some determining factor....but wanted to see if someone knew of a way to do this.

I want to create a shifting scale for numbers.

Let's say I have the number 26000. I want the outcome of this algorithm to be 6500; or 25% of the original number. But if I have the number 5000, I want the outcome to be 2500; or 50% of the original number.

The percentages don't have to be exact, this is just an example.

I just want to have like a sine wave sort of thing. As the input number gets higher, the output number is a lower percentage of the input.

Does that make sense?
