Hello, What is the best way to determine if a float number b is an integer multiple of another float number a, (i.e. b = k a with k an integer)? I wanted to use the following test abs(mod(b, a))<1e-12, but I am confused with the behavior of the mod routine: @show mod(2*0.1, 0.1), mod(3*0.1, 0.1),…

Thank you for your answer. I definitely missed this thread.
