Subject Re: Doubts about function in
Author fabiano_bonin
Now i see they are working. I made a mistake when testing. I was
using truncate(2.111, 2), thinking the function have a second
parameter to specify the precision.

Just for curiosity, how do you truncate numbers to a specif number
of decimal digits?

Something like this?
cast(truncate(2.111 * 100) as double precision) / 100
