## JavaScript program to remove fractional part of a number :

*JavaScript* provides one inbuilt method to remove the fractional part of a number. If you have one *floating-point* number like *1.24* and you need only the *integer* part i.e. *1*, you can use this method. In this tutorial, I will show you how to do that in *JavaScript* with a simple *function*. In the example, I will show you how to do that with different inputs.

## JavaScript Math.trunc :

*JavaScript* provides one method called *Math.trunc()* that takes one *number* as its parameter and returns the integer part of that number. No matter the number is positive or negative, it cuts off the *dot* and everything to the right of it.

If you pass any different type of argument to it, it will implicitly convert it to a number.

## Example of Math.truc() :

```
console.log(Math.trunc(10.123));
console.log(Math.trunc(-11.123));
console.log(Math.trunc('12.123'));
console.log(Math.trunc('13.123xyz'));
console.log(Math.trunc('-14.123'));
console.log(Math.trunc(NaN));
console.log(Math.trunc(undefined));
console.log(Math.trunc('xyzabc'));
console.log(Math.trunc(15));
console.log(Math.trunc(-0));
```

### Output :

It will print the below output :

```
10
-11
12
NaN
-14
NaN
NaN
NaN
15
-0
```
