" The domain of "f(x)=(1)/(sqrt(|x|-x))

Two friends A & B were discussing about domain of greatest integer function y=[x] ,then A said that domain of [x] is R (set of real numbers).Then B expressed that he has doubt in finding the domain of f(x)=(1)/(sqrt([x]-x)) . Then domain of f(x)=(1)/(sqrt([x]-x)) is
