Rounding to 50

Question

Hello all,
i'd like to present some SQL for rounding number to whole 50. SQL code works from Oracle 9iR2 beyond.
Here's the code :
with input as
(select 1125.18 val
from dual)
select val,
case
when round (val) - round (val, -2) >= 25
then round (val, -2) + 50
when round (val) - round (val, -2) < 25
then round (val, -2)
end result
from input;
And result :
VAL RESULT
1125.18 1150

Answer 1

Surely this is easier?
with input as (select 1125.18 val from dual union all
               select 1030.9343 val from dual union all
               select 21.3 val from dual union all
               select 99 val from dual)
select round(val/50)*50
from input;
ROUND(VAL/50)*50
            1150
            1050
               0
             100
