Function map on Node-RED

General

Hi, I'm using this fuction on the Arduino IDE, but I want to use it in Node-RED some documentation that I must see?

This is the function I need to use map but I'm not sure in Node-RED the equivalent for that.

output_value = map(output_value,500,0,0,250);

I use this https://www.arduino.cc/reference/en/language/functions/math/map/ because I was using this function on Arduino to map my values, so I think the Range Node is the equivalent

Use the range node for the nearest equivalent
