FOR WHAT PURPOSE WE USE BOOLEAN???

Question

?????????????????????

Answer 1

Boolean is used in condition testing

Answer 2

Do you know it? - false
Did you write in caps and wrote a lot of '?'? - true

Answer 3

Basicly it is answering/asking "Yes/No"-Questions

Answer 4

Boolean gives only 2 results -
True or False
Right or wrong
Yes or Not

Answer 5

to keep it simple, a boolean is an on off switch.

Maybe your making Mario Bros. You can't jump if you aren't on the ground.

You push the A button...

if(onGround==True)
Jump
if(onGround==False)
No Jump

Your writing a simple while loop. Use a boolean to tell it when to stop.

run=True
while run==True:
loop until run=False

Answer 6

ok thns

Answer 7

This avoids you to use useless conditions. For example :

//without boolean

function test() {
return 0
}
if(test()==0){
//code here
}

//with boolean

function test() {
return true
}
if(test()) { //don't have to check an equality
//code here
}

and if you want to check if the function returns false you can just write : if(!test())

But this can also help you if the function has to return a number resulting of a calculation. If there is an invalid parameter, you can just return false to prevent of the error.

@Antoine Bergerault:
In your last sentence:
I want a number! What is... ?
Function: "False"
Do. Not. Return. Other. Datatypes.
If anybody thinks different, let me know.
