The sum of 2 floating values in postgres gives the result with higher precision. Expected: Actual: The result is having higher precision than expected. The same operation with different set of inputs behaves differently. Here I have reduced the problem statement by finding the 2 numbers for which the issue exists. The actual problem is when I do this on

SQL set floating point precision
For a SQL int that is being converted to a float, how do I set the precision of the floating point number? This is the selection I would like to truncate to two or 3 decimal places: Thanks! Answer In TSQL, you can specify two different sizes for float, 24 or 53. This will set the precision to 7 or
TSQL – make a literal float value
I understand the host of issues in comparing floats, and lament their use in this case – but I’m not the table author and have only a small hurdle to climb… Someone has decided to use floats as you’…
