Checks if a number has any decimals digits
|
|
|
|
- Use the modulo (`%`) operator to check if the number is divisible by `1` and return the result.
|
|
|
|
```js
|
|
const hasDecimals = num => num % 1 !== 0;
|
|
```
|
|
|
|
```js
|
|
hasDecimals(1); // false
|
|
hasDecimals(1.001); // true
|
|
```
