Recently I was working on one of my projects and I encountered one scenario in which I had to check that whether the number is positive or negative according to the number’s nature I had to run the logic and then I came to know about `Math.sign()`

. I should share this thing with you π..

There is a built in fuctinon in javascript `Math.sign()`

, The `Math.sign()`

function returns either a positive or negative +/- 1, indicating the sign of a number passed into the argument. If the number passed into `Math.sign()`

is 0, it will return a +/- 0. Note that if the number is positive, an explicit (+) will not be returned.

*Examples*

```
console.log(Math.sign(5));
// expected output: 1
console.log(Math.sign(-5));
// expected output: -1
console.log(Math.sign(0));
// expected output: 0
console.log(Math.sign("-5"));
// expected output: -1
```

If you find it helpfull please share with your network β .

Happy Coding π !
