# Truncate Number Step

The Truncate Number step rounds a decimal number. You can round it to a certain number of decimal places or turn it into a whole number. This helps make numerical data consistent in your automation processes.

## How to Use the Truncate Number Step

Use this step to round a decimal value and save the result.

### Step 1: Add the Truncate Number Step

1.  Open your process in the Robotiq.ai Process Editor.
2.  Drag the **Truncate Number** step into your workflow.

### Step 2: Set Up Input Parameters

1.  **Step name** (Optional): Give this step a custom name. This helps you find it in your process.
2.  **Source numeric variable** (Required): Pick an existing variable that holds the decimal number you want to round. This variable must be a decimal type.
3.  **Define decimal places to round value** (Required): Type in how many decimal places you want to keep. For example, type `2` to round to two decimal places.

### Step 3: Set Up Output Parameters

1.  **Define variable to store rounded value** (Required): Pick an existing variable or make a new one to save the rounded decimal number. This variable must be a decimal type.
2.  **Define variable to store integer** (Optional): Pick an existing variable or make a new one to save only the whole number part of the rounded number.
3.  **Define variable to store decimal part** (Optional): Pick an existing variable or make a new one to save only the decimal part of the rounded number.

## Parameters Explained

**Step name** (Optional)

-   A custom name for the step in the process editor.
-   Example: `Round_Order_Total`
-   Use this to make your process steps clear.

**Source numeric variable** (Required)

-   The variable that has the decimal number you want to round.
-   Example: `OrderTotal` (must be a decimal type)
-   This is the number you're rounding.

**Define decimal places to round value** (Required)

-   How many decimal places you want in the rounded number.
-   Example: `2` (rounds to two decimal places like 12.34)
-   Set this to `0` to get a whole number.

**Define variable to store rounded value** (Required)

-   The variable where the main rounded decimal result will be saved.
-   Example: `RoundedOrderTotal` (must be a decimal type)
-   This variable will hold the number after rounding.

**Define variable to store integer** (Optional)

-   The variable where only the whole number part of the rounded number will be saved.
-   Example: `OrderTotalInteger`
-   Use this if you need just the whole number.

**Define variable to store decimal part** (Optional)

-   The variable where only the decimal part of the rounded number will be saved.
-   Example: `OrderTotalDecimal`
-   Use this if you need just the fractional part.
