How to use [math.random]

The reference page of math.random has its arguments, constraints and declaration.

This slot returns a random number. Its behavior depends on how many child nodes you give it.

• No children - Returns a random double between 0.0 and 1.0.
• One child - Returns a random integer between 0 and the child’s value, where the upper bound is exclusive.
• Two children - Returns a random integer between the first child’s value, inclusive, and the second child’s value, exclusive. The children are documented as [min] and [max], but the slot uses the first and second child regardless of their names.

Child values are converted to int.
