Hello, postgres [1264904]=# select 123456789.123456789123456::double precision; ┌────────────────────┐ │ float8 │ ├────────────────────┤ │ 123456789.12345679 │ └────────────────────┘ (1 row)
I do not understand why this number is truncated at 123456789.12345679 that is 17 digits and not 15 digits Any idea Fabrice Documentation says: double precision 8 bytes variable-precision, inexact 15 decimal digits precision
