Numeric Functions
The table below lists the numeric functions included in the ODBC scalar function set that can be used with the BASIS ODBC Driver.
Arguments denoted as numeric_exp can be the name of a column (of any numeric type), the result of another scalar function that returns a numeric value, a mathematical operation, or a numeric literal.
Arguments denoted as float_exp can be the name of a column (of type FLOAT, DOUBLE, REAL, or DECIMAL), the result of another scalar function that returns a float value, a mathematical operation, or a numeric literal.
Arguments denoted as integer_exp can be the name of a column (of type signed or unsigned INTEGER), the result of another scalar function that returns an integer value, a mathematical operation, or an integer literal.
