What are Oracle data types?
Each value manipulated by Oracle Database has a datatype. The datatype of a value associates a fixed set of properties with the value. These properties cause Oracle to treat values of one datatype differently from values of another.
What is double data type in database?
Double Type Double types are used when we are not certain of the behavior of our data. The input data is interpreted as floating point integer values. Some data may take more digits to the right of the decimal point. While the storage size of the decimal type is variable, the double type takes 8 bytes storage size.
What is float 126 in Oracle?

What is BLOB data type in Oracle?
A BLOB (binary large object) is a varying-length binary string that can be up to 2,147,483,647 characters long. Like other binary types, BLOB strings are not associated with a code page. In addition, BLOB strings do not hold character data.
Why we use double data type?
