find the zeroes of the function: y = 40sin(2x) - floor(40sin(2x))

where Y,X [itex]\in[/itex] R

I don't exactly know how to handle this problem. My best insight so far is that it is only equal to zero whenever 40sin(2x) is an integer. But even then the distribution of these integers is quite random and I honestly don't know any inverse-floor function.
