SQL for rounding to the nearest value

Question

Hi All,
My Oracle DB version is 10g Release2 and also 11gR1
I have data like below, I need to write a SQL for the below requirement.
ID   RANGE_LOW                RANGE_HIGH
1      50                    55             
2      55                    60
3      60                    63 
4      63                    77 
5      77                    84   The requirement is like I need to check a value between the above range low and high then round it to the nearest value.
Say, for example if I have 68 then the value is rounded to 63 else if 74 then 77 else if its in the middle of two values (70) then rounded to the highest value, here its 77.
Please advice.

hi Purvesh,
I think , you didn't check it properly with requirement of posting. Your query needs to be changed a bit. Please verify againYes, I probably missed or overlooked the last line.
Here is the updated solution then:
with data as
  select 1 id, 50 low, 55 high from dual union all
  select 2, 55, 60 from dual union all
  select 3, 60, 63 from dual union all
  select 4, 63, 77 from dual union all
  select 5, 77, 84 from dual 
chk_val as
  select &val val from dual
select id, low, high,
       val input_value,
       case
        when val < (low + high)/2
          then low
        else
          high
       end round_value
  from data, chk_val
where val between low and high;
ID                     LOW                    HIGH                   INPUT_VALUE            ROUND_VALUE           
4                      63                     77                     70                     77
