In a effort to harmonize as much as possible the conversion behaviors, for some cases, in NativeSql our implementation casting works otherwise than the CAST AS method.
Precisely, when casting float to integer, the default behavior rounds the result, other languages truncate it. That’s why the use of TRUNCATE was implemented when converting float to int. The same implementation was done when converting strings to int (for date represented as string). As for the conversion of date to int, we handled it by assuming the dataset’s timestamp is in TIMESTAMP_NTZ format.
