This document provides an overview of MATLAB formatting and operations on numeric data types. It includes: 1) Examples of formatting numeric values with different precision levels and notations using formats like short, long, hex, etc. 2) Observations on how the precision and byte size of numeric values change based on data type when formatted. 3) Examples of performing basic math operations like addition, subtraction, multiplication on numeric values and the results. 4) Examples of using rounding and remainder functions on integer values and the output. The document demonstrates how to format and manipulate numeric data in MATLAB using different functions and formats.

- 5. Observation from above Formatting (Number1 = 1.23456789), (Number2 = -4.2) Precision of the output values changes as per the format selected. For whole number with decimal point all values has minimum 4 decimal output is generated for short format. For whole number with decimal point all values has maximum 15 decimal output is generated for long format. Format styling can be changed according to the spacing required for output.

- 9. Observations from above Formatting (Number3 = - 1.23456789) Variables of data types (class) can be stored as different bytes according to output required. Precision can be changed of floating point value according to the requirement. Unassigned integers of different data types also can be stored as different bytes.

- 11. Observations – Using Operators To used operators between more than 2 values we have to use operators such as + , - , * , / , ^ etc. Example (a+b+c) Operators can also by using syllables such as plus, minus, times, rdivide, ldivide, etc. Example (plus(a,))
