Representation of Numbers in Matlab

In computers, numbers are classified into three main categories: unsigned integers, signed integers

Positive integer numbers can be represented in Matlab using the unsigned integer classes. Matlab supports four unsigned integer classes which are uint8, uint16, uint32, and uint64. Examples of positive integer numbers are 2, 7, 1023, 12345, etc…

The uint8 class is capable of representing an integer number in the range of 0 to 255. Storing such a number in the computer memory using this class requires one byte.

The uint16 class is capable of representing an integer number in the range of 0 to 65,535. Storing such a number in the computer memory using this class requires two bytes.

The uint32 class is capable of representing an integer number in the range of 0 to 4,294,967,295. Storing such a number in the computer memory using this class requires four bytes.

The uint64 class is capable of representing a number in the range of 0 to 18,446,744,073,709,551,615. Storing such a number in the computer memory using this class requires eight bytes.
