Random number

Overview

The Random number node generates a random integer within a configured range on each flow execution. It provides dynamic input for testing and simulation purposes.

Use Random number when:

• You need to simulate unpredictable numeric inputs for testing flow stability.
• You want to randomize flow parameters across multiple executions.

⚠️ Warning

Ensure that Maximal limit value is always greater than or equal to min_limit to avoid generation errors.

Outputs

Name	Type	Description
output	number	The generated random integer.

Parameters

Parameter	Default	Valid values	Tunable
Minimal limit value	0	integer	✅
Maximal limit value	100	integer >= 1	✅

Minimal limit value

The lower bound for the generated random number.

Maximal limit value

The upper bound for the generated random number. This value must be at least 1.

Example

Simulating sensor jitter

To test how a flow handles fluctuating sensor data, a Random number node is used to inject small, random variations into a numeric value.

Configuration:

• Minimal limit value: 0
• Maximal limit value: 10

Result: A different integer between 0 and 10 is generated for every flow pass.
