Subtraction return in postgres

0

I have a table with a field called VALUE double precision, and a function that returns another data also double precision, what happens is that if I do

select (VALUE - function ()) the result in which case both the VALUE and the result of the function are equal, the result is 2.27373675443232e-013

I found it very strange and I'm not sure what to do, I've already done some tests with conversions and rounding and nothing

Does anyone have any idea what might be happening?
