Each of these data types serves a specific purpose and can be used to optimize memory usage and computational performance in your system.


A BIT represents a binary digit, which is the smallest unit of data in a computer system. It can hold one of two values.


"Signed" means it can represent both positive and negative values.

"Unsigned" means it can only represent non-negative whole numbers.


Floating point numbers are designed to represent real numbers, allowing for a wide range of values with varying degrees of precision. The range and precision of these numbers depends on the specific implementation.
