6.1.7BIGINT

The HDFql BIGINT data type stores values between -9,223,372,036,854,775,808 and 9,223,372,036,854,775,807 and occupies 8 bytes in memory. It represents the data type of an HDF5 H5T_NATIVE_LLONG dataset/attribute or of a result set that stores elements of this type (which can be retrieved using the HDFQL_CURSOR_GET_BIGINT function when working with cursors). Depending on the programming language supported by HDFql, the BIGINT data type is represented by:

• In C, the “long long” data type.
• In C++, the “long long” data type.
• In Java, the “long” data type (or corresponding wrapper class “Long”).
• In Python, the “int64” NumPy data type.
• In C#, the “Int64” data type (or corresponding alias “long”).
• In Fortran, the “INTEGER(KIND = 8)” data type.
• In R, the “integer64” bit64 data type.
• In MATLAB, the “int64” data type.
