Обсуждение: simple SQL question

I have a column with the following values (example below)

5673
4731
4462
5422
756
3060

I want the column to display the numbers as follows:

56.73
47.31
44.62
54.22
7.56
30.60

I have been playing around with string functions but cannot seem to
figure out a quick solution. Does anyone have any suggestions?

Please let me know.

Thanks.

What about:

pgloader=# select a::float / 100 from (values(5673), (4731), (4462), (5422),
(756), (3060)) as x(a);
 ?column?

     30.6

   Are these numbers that will be used in calculations, or are they strings?

   Numeric(4,2) will do this. Also, whatever the UI you are using in your
application can make the translation from display format to storage format.

   If they are strings, why not enter and store them with the decimal point?
