# node-red-node-random

A <a href="http://nodered.org" target="_new">Node-RED</a> node that when triggered generates a random number between two values.

## Install

Either use the Manage Palette option in the Node-RED Editor menu, or run the following command in your Node-RED user directory - typically `~/.node-red`

    npm i node-red-node-random


## Usage

A simple node to generate a random number when triggered.

If set to return an integer it can include both the low and high values.
`min <= n <= max` - so selecting 1 to 6 will return values 1,2,3,4,5 or 6.

If set to return a floating point value it will be from the low value, up to, but
**not** including the high value. `min <= n < max` - so selecting 1 to 6 will return values 1 <= n < 6 .

You can dynamically pass in the 'From' and 'To' values to the node using msg.to and/or msg.from. **NOTE:** hard coded values in the node **always take precedence**.

**Note:** This returns numbers - objects of type **number**.
