Question

math is not my strongest side so please someone help me with this formula:
I have an ascending variabel y that goes to infinity.

When:

y < 100 I want x = 1,
100 >= y < 200 I want x = 2,
200 >= y < 300 I want x = 4,
300 >= y < 400 I want x = 8
400 >= y < 500 I want x = 16

and so on.

Thanks in advance

Answer 1

x = 2 ^ (y / 100)

or if y is not an integer (which would amount to integer division).

x = 2 ^ Floor(y / 100)
