Step math function

Question

Hi

I need function which returns:

• for any number from range => result

  [0.001,0.01) => 0.01

  [0.01,0.1) => 0.1

  [0.1,1) => 1

  [1,10) => 10

  [10,100) => 100

  etc.

My first idea was to use if, but this the worst way. Is there a simple solution?

Answer 1

10^(floor(log(x) + 1))
