ya peter but my client is asking me like that.
it is possible to round to 15 if it is greter than 10? (i.e. 11 -15 to 15. 16-20 to 20)This:
with my_tab as (select 12.5 num from dual union all
                select 13 num from dual union all
                select 12.49 num from dual union all
                select 15.13 num from dual union all
                select 10 num from dual)
select num,
       ceil(num/5)*5 rounding_up,
       ceil(floor(num)/5)*5 rounding_mostly_up
from my_tab
       NUM ROUNDING_UP ROUNDING_MOSTLY_UP
      12.5          15                 15
        13          15                 15
     12.49          15                 15
     15.13          20                 15
        10          10                 10Edited by: Boneist on 26-Feb-2009 11:48
added in second column, depending on whether 15.<something> is supposed to round up to 20 or down to 15
