Hi. Can someone explain to me what is the difference between those two functions:

PHP Code:

new Float:array[3] 


PHP Code:

new bool:array[3] 


Those functions are intended for saving information. But what is the difference between Float and Bool? How is a plugin that uses Bool different than a plugin that uses Float?

They are not functions, they are variables/arrays. You are correct in that they store information.

A Float holds a floating point decimal: 3.146534
A bool holds true or false

It depends on what you need to save, obviously:
For the bool, you could store whether or not a player is connected, is a bot, etc
For the Float, you could store any numerical value that is a decimal (non-integer)
