/home takes you to integer rounded co-ordinates

Using /home will take the user to a the integer rounded co-ordinates. /gcheckold x.xxx y.yyy z.zzz should take you to floating point coords but only does integers. I expected to be taken to the (near) exact spot where /sethome was used but instead it is putting me in the corner of the block I stood on when using the /sethome command (It is rounding the co-ordinates).
