ALL geogrid.exe, ungrib.exe and metgrid.exe ran successfully but after metgrid.exe I got the following IEEE note.
! Successful completion of metgrid. !
Note: The following floating-point exceptions are signalling: IEEE_OVERFLOW_FLAG IEEE_UNDERFLOW_FLAG IEEE_DENORMAL

Is there any problem in WPS or is it normal.
Is there will be any bad effect of this in wrf run.
This should not be a problem. This message prints out with certain compilers, and was originally put in the code for testing purposes. You should be perfectly fine to continue to run real and wrf.
