I want to round up number to three decimal places.
but it failed when trunc(52.5) = 52.5 and I wanted 52.500
I think I should use to_char(x,9999.999) but wait may be the numbers invlove will be very small or it could be really large so do you think I should use
t0_char(x,999999999999999.999) or is there any other good idea????
