In sql server my division select cast(3 as float)/10 is 0.29999999999.
But in postgres select cast(3 as float8)/10 is 0.3. How to get result like
sql server?
Thank you. Sorry for my english

I believe you can control what precision is used in printing the float
results with extra_float_digits. I believe setting it to 2 will give a
0.29... result however it has more 9s than the above.
