What is the difference between TRUNC and ROUND?
The ROUND() is used to round a numeric field to the nearest number of decimals specified. e.g. 56 is nearer to 60 than 50 hence it will return 60. e.g. If instead of 56 you use 54 then 54 is nearer to 50 and it will return 50. TRUNC() returns a number truncated to a certain number of decimal places.
