A couple of other examples are also presented. Seven examples involving one repeated variable and three examples involving two repeated variables are shown. Along the way I comment on the common types of user mistakes made in specifying these kinds of models and show how to overcome the ...
Another way to see the difference in exact and approximate value handling is to add a small number to a sum many times. Consider the following stored procedure, which adds.0001to a variable 1,000 times. CREATEPROCEDUREp()BEGINDECLAREiINTDEFAULT0;DECLAREdDECIMAL(10,4)DEFAULT0;DECLAREfFLOATDEFAU...
