initFloorplan() always snaps to grid

[antonblanchard]

I was looking through warnings during a tape out and saw:

[WARNING IFP-0028] Core area lower left (5.520, 10.880) snapped to (5.520, 10.880).

I printed out the values, and it does look like the size of my macro is not a multiple of site:

clx 5520
core_lx 5.5199999860633405e-06
cly 10880 
core_ly 1.0879999972530641e-05

But it also seems like the comparison will never be true, because we are comparing a value that has been converted to Dbu:

      int clx = divCeil(metersToDbu(core_lx), site_dx) * site_dx;
      int cly = divCeil(metersToDbu(core_ly), site_dy) * site_dy;

      if (clx != core_lx || cly != core_ly) {

I presume this is harmless, but it would be nice to fix so the warning goes away.

I was fixing up ifp for python and I think I've eliminated this problem in the process (both values are dbu now). Would you verify this is ok to close? There is no test case.

Thanks @maliberty, I'm no longer seeing this.
