Which notation are you unfamiliar with? I'll just take a stab at it now and assume you haven't seen $\lfloor x \rfloor$ before; these brackets represent the "floor function" which rounds down to the nearest integer.

For example
$$\lfloor 1.2 \rfloor = 1$$
$$\lfloor 0.999 \rfloor = 0$$
$$\lfloor 4 \rfloor = 4$$
