Excel offers a wide range of number formats to choose from, including:

• Number: This format is used for general numeric data, and allows you to specify the number of decimal places to display.
• Currency: Use this format to display monetary values, with a specified currency symbol and decimal places.
• Percentage: This format displays numbers as percentages, multiplying the cell value by 100 and adding a percentage symbol.
• Date and Time: Excel provides several date and time formats for displaying date values, time values, or combined date and time values.
• Custom: With custom number formats, you have full control over how the data is displayed, allowing you to create specific formats to meet your needs.

C. Examples of when to use different number formats

Knowing when to use different number formats can help you present your data in a clear and meaningful way. For example:

### Number Format:

• Use the Number format to display sales figures, quantities, or any other general numeric data.

### Currency Format:

• When working with financial data, such as revenue or expenses, use the Currency format to clearly display monetary values.

### Percentage Format:
