[firebird-support] double precision remove last 2 numbers

[hamacker sirhamac...@gmail.com [firebird-support]]

Hi All,

I do this update:
UPDATE CV SET
  perc_lucro=42.503064336972848
WHERE (id_cv=57528)

Then  I do a select and 'perc_lucro' was change to 42,5030643369728 after
updated, two last numbers disappear.
Why?
perc_lucro is double precision type.
