Ah, perfect, thanks! I have a line graph that displays millions of dollars. I wanted to set the Y axis to the farthest multiple of $50m over and under the current day’s value. This did the trick niceley, and now I don’t have to manually update and hard code the axis min & max every few months.

hi
no problem either

i ran

update table 1
set minnumber=minnumber -5 where min(number)like ‘%%%2.5%%%’
update table 1
set minnumber=minnumber -5 where min(number)like ‘%%%7.5%%%’

so whereas before any number ending like %%%2.5%%% was getting rounded up to 6005 when i wanted it as 6000 and any number ending up like ‘%%%7.5%%%’was getting rounded up to 6010 when i wanted it as 6005 now with the update function everything is corrected.
(isn’t this a nice way to get around the round up problem so simple yet logical)
i know it an extra step but it works and that should count even for a newbielike me (second week learning sql:))

beats spending the next few days trying to work out a formula im sure there is one but time dictates if it works move on.

hi found problem if the number equals 6007.5000 or 6002.5000
will always round up ,i used

minnumber= CAST (cast ((round(min(number) *20000,-5)) as decimal )/20000 AS NUMERIC (8,4))

this sets the number intervals in 5.0 point increments and it always rounds up if number is at ‘%%%2.5%%%’ and ‘%%%7.5%%%’(ie, midpoint of the 5 point intervals)

how can i set these two numbers so they show as 6000.0000 and 6005.000 respectively whilst not changing the rest
any ideas

sixes and sevens no more i just multiplied the number far out then round((),-5) and divide by same number so now i get the numbers from 6003 to 6007 shown as 6005 and 6008-6112 shown as 6010, 6113 to 6117 as 6015 and so on….
