## Mastering Precision in Excel

**I’m an Excel enthusiast**. I realize how vital accuracy is to get accurate results. In this article, I’ll dive deeper into the complexities of **Excel precision**. We’ll begin with an intro discussing why it’s important and how it affects your worksheets. Then, we’ll differentiate between the types of precision available in Excel. This will help you decide which one you require to attain the right balance between accuracy and complexity. By the end, you’ll be on your **way to mastering Excel’s precision** and making precise spreadsheets without any difficulty.

### Introduction to Excel precision

**Excel precision is important**. It affects numbers’ calculations and display. By default, **15 digits**. Often, that’s too many. Errors and confusion may occur. Limiting the digits saves time and keeps spreadsheets organized. To do that, adjust the **Number Format** in **Home tab**.

It’s worth noting, Microsoft Excel has been around since 1985. It’s a widely used spreadsheet program. Now, let’s look at **types of precision** in more depth.

### Differentiating between types of precision

The table below shows the different types of precision in Excel.

Precision Type | Description | Example |
---|---|---|

Display Precision | How many decimal points are shown in a cell | 10.5678 = 10.57 |

Calculation Precision | How many decimal points a formula uses in its calculations | =SUM(1.12, 2.98) = 4.1 |

Storage Precision | The actual number stored in a cell, which could be more precise than what’s displayed or used in calculations | 5/3 = 1.666666667 but is stored as 1.66666666666667 |

**Display precision** is what appears on the outside, and **calculation precision** is what happens internally in Excel. **Storage precision** is what’s stored by Excel, which can differ from both display and calculation precision.

You should be careful when limiting or rounding off numbers. Too much decimal points can cause confusion and clutter in your results.

The Mars Climate Orbiter mission in 1999 is an example of why differentiating between types of precision matters. Incorrect calculations, due to different units, caused the craft to crash instead of orbiting Mars.

Now, let’s look at techniques to control precision in Excel without losing accuracy or data.

## Techniques to Control Precision in Excel

Ever had a miscalculation in your Excel sheet? It can be annoying. You can waste time and make costly mistakes. Fortunately, there are techniques to control precision. Here, I will explore **3 sub-sections that show how to limit precision**. We’ll look at adjusting decimal places, using the ROUND function, and the ROUNDUP function. Whether you’re new to Excel or a pro, these techniques can help prevent miscalculations and make your work easier.

### Limiting Precision by Adjusting Decimal Places

**To limit precision in Excel, these steps can be taken:**
