Division ( / ) not giving my answer in postgresql

Question

I have a table software and columns in it as dev_cost, sell_cost. If dev_cost is 16000 and sell_cost is 7500

Answer 1

You can also cast your variable to the desired type, then apply division:

 SELECT (dev_cost::numeric/sell_cost::numeric);

You can round your value , and specify the number of digits after point:

SELECT TRUNC((dev_cost::numeric/sell_cost::numeric),2);
