How to convert numeric value to boolean?

If you are sure that the input is int you can directly apply 0 or 1 to .checked = status; (even .prop('checked', status) ) (as @Sergio explained):

var status = 1; //valor recebido

$("#status").prop('checked', status);

But for other cases where auto-conversion does not exist, you can use !! as long as you are sure to be int :

var status = 1; //valor recebido

$("#status").prop('checked', !!status);

Or so using "ternary operator":

var status = 1; //valor recebido

$("#status").prop('checked', status ? true : false);

Now if you are not sure if you are getting a% s, you can check like this:

var status = '1'; //valor recebido

$("#status").prop('checked', status == '1');

If you just want to "convert" integers to Booleans:

var status = 1;

console.log('Com ==', status == '1'); //Este talvez seja o mais garantido
console.log('Com !!', !!status);
console.log('Com ternário', status ? true : false);

tests the type of this variable first. If it is string it will always give true. Check with:

console.log(typeof status, status);

To be sure, use Number(status) , or status == '1' ? true : false .

$("#status").prop('checked', status == '1' ? true : false);  

Examples:

var status = '1';
$('#statusA').prop('checked', Number(status));
$('#statusB').prop('checked', status == '1' ? true : false);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><inputid="statusA" type="checkbox">
<input id="statusB" type="checkbox">
<input id="status_controle" type="checkbox">

I would most likely do something like this:

var status = 1; // value received

$ ("# status") .pprop ('checked', Number (status)? true: false);

Using same ternary, and converting the value always into a Number, in case a value above 0 would be true, otherwise it would be false.
