Performing joins in PROC SQL and using column(s) in the WHERE or ON clause that have very long lengths might result in the following errors: ERROR: Floating Point Zero Divide. ERROR: Termination due to Floating Point Exception In SAS 9.1.3, these errors occur when the length of the character columns was between 31,091 and 32,609.

The http://support.sas.com/kb/34545 source of the error is that for the data at hand, the underlying linear program is very sensitive to small numerical perturbations and zero divide errors might occur at different quantiles on different hardware configurations. This error was initially reported in the experimental SAS 9.1.3 release, but may also occur in SAS9.2. The log file may show the following error messages and note: ERROR: Floating Point Zero Divide. ERROR: Termination due to Floating Point Exception NOTE: The SAS System stopped processing this step because of errors. In some cases, placing all binary independent variables in the CLASS statement may circumvent the problem. A Hot Fix is avaible for this problem; see the Hot Fix tab.

following error messages in SAS after creating a table using SQL based on a SASHelp table: ERROR: Floating Point Zero Divide. ERROR: Termination due to Floating Point Exception This http://blog.cswenson.com/2011/06/unusual-sas-error-message.html strange set of errors is not well documented and, as I eventually found out, has nothing to do with my original query: proc sql; create table _test_ as select * from sashelp.vtable where upcase(libname)="SPECIFIC_LIBNAME" ; quit; Where "SPECIFIC_LIBNAME" was a macro variable containing the libname I wanted information about. The solution to this problem was to clear a particular library that consisted only of views. This floating point library's members were generated prior to the above step, and may have somehow contributed to the problem within the SASHelp metadata. In general, it may be a good practice to review the libraries and their sizes when encountering problems with the SASHelp library, which contains a great deal of metadata on SAS libraries. For this set of errors, however, this solution will probably not always work. It floating point zero would appear that the problem is related to extensions of SAS that are dependent on external sources. In this case, it may have been the SQL procedure. This does seem strange, since SQL is a widely-used standard. Clearing the previously-created library may have cleared up an exception caused by a large amount of data in the SASHelp table that was not accounted for in the manner in which SAS implemented the SQL standard or the proprietary extensions of it.
