Is it possible to get different results if I use strictfp using docker installed on different OS?

Question

I use some double math operations without strictfp in my code.

I run docker on different OS but everywhere I use the same dockerFile.

Is it posssible to get different results in my math operations?

P.S.

I know that Strictfp ensures that you get exactly the same results from your floating point calculations on every platform. But I am not fully sure what does it mean 'platform'
