What is the "Official Way" to discover the distance between two points in the E-Toy environment?

I don't know how to tile square root, but if you go into textual mode (click on the script name in the script box, and choose to see it textually), you can get square root. The square root message is "sqrt" and it goes AFTER the value that you want to get the square root of. 4 sqrt will return 2.0
