Question: What Are The Data Types In SQL Server?

What is data type float?

The FLOAT data type stores double-precision floating-point numbers with up to 17 significant digits.

FLOAT corresponds to IEEE 4-byte floating-point, and to the double data type in C.

The range of values for the FLOAT data type is the same as the range of the C double data type on your computer..

What is a long data type?

Long is a data type used in programming languages, such as Java, C++, and C#. A constant or variable defined as long can store a single 64-bit signed integer. Because the long data type is signed, the possible integers range from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807, including 0. …
