Every good system should have command called bc. Here is what it gives: bc 1.06 Copyright 1991-1994, 1997, 1998, 2000 Free Software Foundation, Inc. This is free software with ABSOLUTELY NO WARRANTY. For details type `warranty'. scale=9 -201326592.-.589934592 -201326592.589934592 So, DBMS_METADATA.GET_DDL will give you -201326592.589934592 which is a perfectly legal number belonging to R. It is, of course, completely usless but it is completely legal and you don't even need Taylor series to represent it. I am looking forward to the moment when Oracle routines will start returning complex numbers to use as input to "create" commands. That will be completely in accordance with the super-string theory according to which space-time continuum has 11 dimensions. For those who don't remember high school, complex numbers are algebraic closure of R and each number is represented as a sum of its real and imaginary part. The phrase "algebraic closure" means, of course, that every polynomial with the coefficients in C has at least one solution in the field C. Now I've been as helpful as the Oracle Corp. with its return values. Am I great or what? -- Mladen Gogala Ext. 121 -----Original Message----- From: Cornio, Georgette Ms USACFSC [mailto:Georgette.Cornio@xxxxxxxxxxxxx] Sent: Wednesday, October 12, 2005 12:15 PM To: 'oracle-l@xxxxxxxxxxxxx' Subject: RE: tablespaces ddl extract script When I run this on my 9.2.0.7 system, which has 8GB datafiles, it gives this number from the GET_DDL, -201326592.-.589934592 What gives ???
