Formating the number column

Question

how to format
126.810 as 1268100
23.50 as 0235000
fractional part should be 4 digit and integer should be 3 digit.

Answer 1

You need to multiply by 10000 first and then format using to_char, eg:
with my_tab as (select 126.810 num from dual union all
                select 23.50 num from dual union all
                select 0.02 num from dual)
-- end of mimicking data in a table called my_tab
-- check out the SQL below
select num, to_char(num*10000, '0999999') formatted_num
from   my_tab;
       NUM FORMATTED_NUM
    126.81  1268100    
      23.5  0235000    
       .02  0000200ETA: If you could have larger numbers, then something like:
with my_tab as (select 126.810 num from dual union all
                select 23.50 num from dual union all
                select 123456789.9854 num from dual union all
                select 0.02 num from dual)
-- end of mimicking data in a table called my_tab
-- check out the SQL below
select num, to_char(num*10000, 'fm9999999990999999') formatted_num
from   my_tab;
       NUM FORMATTED_NUM   
    126.81 1268100         
      23.5 0235000         
123456790 1234567899854
