# Tableau Math Functions

Tableau provides various Math and Trigonometric Functions to perform mathematical operations on our data. They are FLOOR, CEILING, ABS, DIV, POWER, SQRT, SQUARE, MIN, MAX, SIN, COS, TAN, ACOS, ASIN, ATAN, ATAN2, LN, LOG, etc. In this article, we show how to use Tableau Math Functions with examples.

To demonstrate these Tableau Math Functions, we are going to use the below-shown data. As you can see, there are nine records in this table.

Remember, this is an Excel Worksheet. So, Please refer Connecting to the Excel Files article to understand the connection settings.

## Tableau Math Functions

The following examples will show you the list of Math Functions in Tableau

### ABS

The Tableau ABS function is used to return the absolute positive value and the syntax of this ABS is:

`ABS(number)`

To demonstrate these math functions, we use Calculated Fields. To create a calculated field, navigate to Analysis Tab, and select Create Calculated Field… option.

Once you click on the Create Calculated Field… option, the following window will open. Here, we renamed the default calculation name as ABS.

### ATAN2

Tableau ATAN2 function is to calculate arc Tangent of two given numbers and the syntax of this ATAN2 is:

`ATAN2(y_number, x_number)`

Below statement will find the Arc Tangent value of Sales amount and Standard cost

`ATAN2([Standard Cost], [Sales Amount])`

### COT

Tableau COT function will calculate the Cotangent value and the syntax of this COT is:

`COT(Number)`

It will find Cotangent value of Service Grade

`COT([Service Grade])`

### Tableau DEGREES Function

The Degrees function will convert Radians to Degrees and the syntax of this Degrees is:

`DEGREES(Number)`

`DEGREES([Service Grade])`

Let me add this Degrees field to Measures shelf

`RADIANS(Number)`

It will convert the degrees value in Sales Amount to Radians

`RADIANS([Service Grade])`

### Tableau EXP Function

The EXP function returns e raised to the power of the user-specified number and the syntax of this EXP is:

`EXP(Number)`

It finds e power service grade

`EXP([Service Grade])`

Let me add this EXP field to Measures shelf

### Tableau SQUARE Function

The Tableau Square function finds the square of a given number and the syntax of this Square Function is:

`SQUARE(Number)`

It will find out the square of the tax amount

`SQUARE([Tax Amt])`

Let me add this SQUARE field to Measures shelf

### Tableau SQRT Function

The Tableau Sqrt function finds the square root of a given number and the syntax of this Sqrt is:

`SQRT(Number)`

It will find the square root of Sales amount

`SQRT([Sales Amount])`

Let me add this SQRT field to Measures shelf

### Tableau ROUND Function

The Tableau Round function returns the nearest integer value. It accepts the second argument (optional) to specify the number of decimals. The syntax of this Round Function is:

`ROUND(Number, no_of_decimals)`

For example,

• ROUND(248.6759) = 249
• ROUND(248.6759, 1 ) = 248.7
• ROUND(248.6759, 2 ) = 248.68

Below statement will round the Standard Cost values to the nearest integer

`ROUND([Standard Cost])`
