* Convert all remaining float4 and float8 functions to new fmgr style.Tom Lane2000-08-01
| | | | | | At this point I think it'd be possible to make float4 be pass-by-value without too much work --- and float8 too on machines where Datum is 8 bytes. Something to try when the mood strikes, anyway.
* bpchar, varchar, bytea, numeric are toastable --- if you initdb, whichTom Lane2000-07-29
| | | | | | I did not force. I marked numeric as compressable-but-not-move-off-able, partly to test that storage mode and partly because I've got doubts that numerics are large enough to need external storage.
* Revise aggregate functions per earlier discussions in pghackers.Tom Lane2000-07-17
| | | | | | | | | | | There's now only one transition value and transition function. NULL handling in aggregates is a lot cleaner. Also, use Numeric accumulators instead of integer accumulators for sum/avg on integer datatypes --- this avoids overflow at the cost of being a little slower. Implement VARIANCE() and STDDEV() aggregates in the standard backend. Also, enable new LIKE selectivity estimators by default. Unrelated change, but as long as I had to force initdb anyway...
* Clean up #include's.Bruce Momjian2000-06-15

* Big warnings cleanup for Solaris/GCC. Down to about 40 now, butPeter Eisentraut2000-06-14
| | | | | | | | | | | we'll get there one day. Use `cat' to create aclocal.m4, not `aclocal'. Some people don't have automake installed. Only run the autoconf rule in the top-level GNUmakefile if the invoker specified `make configure', don't run it automatically because of CVS timestamp skew.
* Another batch of fmgr updates. I think I have gotten all old-styleTom Lane2000-06-13
| | | | | functions that take pass-by-value datatypes. Should be ready for port testing ...
* Latest round of fmgr updates. All functions with bool,char, or int2Tom Lane2000-06-05
| | | | | | | inputs have been converted to newstyle. This should go a long way towards fixing our portability problems with platforms where char and short parameters are passed differently from int-width parameters. Still more to do for the Alpha port however.
* Ye-old pgindent run. Same 4-space tabs.Bruce Momjian2000-04-12

* Extend numeric_round and numeric_trunc to accept negative scale inputsTom Lane2000-03-13
| | | | | | (ie, allow rounding to occur at a digit position left of the decimal point). Apparently this is how Oracle handles it, and there are precedents in other programming languages as well.
* Add numeric <-> int8 and numeric <-> int2 conversion functions, as wellTom Lane2000-02-24
| | | | | | | | | | as a unary minus operator for numeric. Now that long numeric constants will get converted to NUMERIC in early parsing, it's essential to have numeric->int8 conversion to avoid 'can't convert' errors on undecorated int8 constants. Threw in the rest for completeness while I was in the area. I did not force an initdb for this, since the system will still run without the new pg_proc/pg_operator entries. Possibly I should've.
* Fix bugs in NUMERIC ceil() and floor() functions. ceil(0) returned 1,Tom Lane2000-01-20
| | | | | and both would insert random junk digits if given an input that was an exact multiple of 10.
* numeric_in accepts exponents; numeric to int4 rounds; float4/8 to numericTom Lane2000-01-18
| | | | | | is considerably more robust and accurate than it used to be. Also, get rid of numeric's private allocation freelist, which is no longer a win since Jan rewrote palloc.
* Clean up problems with rounding/overflow code in NUMERIC, particularlyTom Lane2000-01-15
| | | | | the case wherein zero was rejected for a field like NUMERIC(4,4). Miscellaneous other code beautification efforts.

* Use sprintf() to convert float8 to a string during conversion to numeric.Thomas G. Lockhart1999-05-04
| | | | | Original code used float8out(), but the resulting exponential notation was not handled (e.g. '3E9' was decoded as '3').
