How to Round Off in Notion to Any Decimal Numbers (Easy Method)

Rounding numbers in Notion can feel tricky at first, especially if you’re not familiar with formulas. One small error, like leaving out a parenthesis or typing the wrong symbol, can mess up your whole table or budget tracker.

But once you learn how rounding works, it becomes simple. You’ll be able to control how many decimal places appear in your numbers, making your data look clean and professional.

Notion doesn’t have a built-in “round” button like a calculator. Instead, it uses formulas that do the same job. With just one short expression, you can round any number to one, two, or even five decimal places. This helps you keep your workspace neat and your data easier to read, whether you’re tracking money, time, or scores.

In this guide, you’ll learn the easiest way to round off numbers in Notion to any decimal value. You’ll see clear examples and ready-to-use formulas that you can copy right into your pages. By the end, you’ll be able to make your Notion tables look sharp, organized, and error-free.

Set Up Your Database and Formula Column

Step 1: Open or Create a Notion Database

Start by opening a database in Notion that has a Number property type column containing the values you want to round.

For this guide, we’ll use a sample Expense Tracker The database has:

A Title column for the month.

An Amount column set to the Number property type, containing values with three decimal places.

We’ll demonstrate how to round these numbers to 0, 1, and 2 decimal places.

⚠️ Note: Rounding formulas only work on Number properties. If your column is set to Text, the formula won’t work. Make sure the target column uses the correct property type.

Step 2: Create a Formula Column for Rounding

Next, create a new column where you will enter your rounding formula:

Click the ➕ icon next to the rightmost column in your database.

Scroll down in the menu and select Formula as the property type.

Name the new column. For example:

“Round to 0 decimal places”

This column will calculate the rounded values based on the Amount column.

Step 3: Access the Formula Window

To enter your formula:

Click Edit property on the new formula column.

The formula window will open. Here, you can type your rounding expression, like: round(Amount)

This interface is where all Notion formulas are created. Once you enter the formula, the column will automatically display the rounded numbers according to the logic you choose (whole number, 1 decimal, 2 decimals, etc.). This shows to round the amount as whole number

💡 Tip: You can create multiple formula columns if you want to show the same values rounded to different decimal places for easy comparison.

How to Round Numbers to Specific Decimals in Notion

Round to One Decimal

To keep one decimal place, use: round(Amount * 10)/10

Here’s how it works: multiplying by 10 moves the decimal one place to the right, round() rounds it, and dividing by 10 moves it back. For example, 3.67 becomes 3.7.

Use this for scores, ratings, or averages where one decimal gives enough detail without clutter.

Round to Two Decimals

To round to two decimal places, use: round(Amount *100)/100

This moves the decimal two places, rounds, then restores it. A value like 3.678 becomes 3.68.

Two-decimal rounding is perfect for currency, budgets, percentages, and financial summaries. It ensures numbers look consistent and professional.

Round to Custom Decimals

For more precision, extend the same pattern:

round(prop *1000)/1000 - For 3 decimals

round(prop *10000)/10000 - For 4 decimals

Every extra zero adds one decimal place. This is useful for scientific measurements, technical data, or analytics where small differences matter.

Negative Numbers

Rounding negative numbers in Notion works the same way, but it rounds toward the nearest whole number, not away from zero.

round(-4.49) → 4

round(-4.51) → 5

round(-4.5) → 4

This small detail is important for budgets, debts, or any values below zero. Knowing it keeps your results correct and predictable.

With this approach, you can round any number in Notion to exactly the precision you need. Your reports stay clear, your dashboards tidy, and your numbers accurate.

Round() Vs. Floor() Vs. Ceil()

Notion gives you three rounding functions, each with a different behavior. Knowing which one to use helps keep your data accurate and your calculations reliable.

round() - Nearest Number

The round() function rounds a number to the nearest integer. Numbers with decimals from 0 to 0.49 round down. Numbers from 0.5 to 0.99 round up.

For example:

round(3.2)→ 3

round(3.8)→ 4

Use round() for general-purpose rounding. It works well when you need mathematically correct results, like averaging scores, calculating totals, or summarizing data in reports.

floor() - Always Down

The floor() function always rounds down, no matter the decimal.

Examples:

floor(3.1) → 3

floor(3.9) → 3

floor(-3.1) → 4

Notice how negative numbers round toward negative infinity. floor() is useful when you need full units only, such as counting complete pages, assigning items in whole numbers, or calculating age from a birthdate.

ceil() - Always Up

The ceil() function always rounds up to the next integer.

Examples:

ceil(3.1) → 4

ceil(3.9) → 4

ceil(-3.9) → 3

Negative numbers round toward zero. Use ceil() when you need minimum coverage or resources, like packing boxes, allocating seats, or ensuring enough capacity.

Understanding these three functions lets you pick the right method for every scenario. By this your numbers stay precise, your reports reliable, and your dashboards consistent.

Quick Reference Table

This table lets your readers see everything at a glance: whole numbers, decimals, negatives, and alternate rounding methods.

Rounding Type	Formula	Example Input	Example Output	Notes / Use Case
Round to Whole Number	`round(prop("Value"))`	23.6	24	For totals, counts, or simple integer values.
Round to 1 Decimal	`round(prop("Value") * 10) / 10`	3.67	3.7	Ideal for ratings, averages, or scores with one decimal.
Round to 2 Decimals	`round(prop("Value") * 100) / 100`	3.678	3.68	Perfect for currency, budgets, and percentages.
Round to 3 Decimals	`round(prop("Value") * 1000) / 1000`	3.6784	3.678	Useful for scientific or analytical data.
Round to 4 Decimals	`round(prop("Value") * 10000) / 10000`	3.67845	3.6785	High-precision scenarios.
Negative Numbers	`round(prop("Value"))`	-4.49	-4	Rounds toward the nearest whole number, not away from zero.
Ceil (Emulated)	`-round(-prop("Value"))`	3.2	4	Always rounds up. Useful for minimum required quantities.
Floor (Emulated)	`round(prop("Value") - 0.5)`	3.7	3	Always rounds down. Useful for full units, pagination, or age calculations.

Final Thoughts

In this article, we have seen how rounding numbers in Notion can be handled with simple formulas. The round() function lets you round to the nearest whole number or, with a small multiplication/division trick, to one, two, or more decimal places. This keeps your tables clean, precise, and easy to read.

We have also looked at how negative numbers behave, rounding toward the nearest whole number, and how you can emulate floor() to always round down or ceil() to always round up. These methods give you full control over your data.

By applying these techniques, you can make your Notion dashboards organized, your reports accurate, and your calculations consistent. Whether you are tracking money, scores, percentages, or technical data, these rounding methods ensure your numbers are clear and professional.

Frequently Asked Questions

How to round a number in Notion?

Use the round() function in a formula column. For example, round(prop("Value")) rounds a number to the nearest whole number.

How to round off to 2 decimal places in Notion?

Multiply the number by 100, round it, then divide by 100: round(prop("Value") * 100) / 100. This keeps two digits after the decimal.

Can I round negative numbers in Notion?

Yes. Negative numbers round toward the nearest whole number, not away from zero. For example: round(-4.49) → -4, round(-4.51) → -5.

Can I round numbers in Notion text columns?

A: No. The round() function only works with Number property columns. Make sure your target column is set to Number.
