# JavaScript Convert a Value to Safe Integer

A safe integer is an integer that:

- Can be exactly represented as an IEEE-754 double precision number, and
- Whose IEEE-754 representation cannot be the result of rounding any other integer to fit the IEEE-754 representation

`Math.max()`

and`Math.min()`

to find the closest safe value.`Math.round()`

to convert to an integer.

```
const toSafeInteger = num =>
Math.round(
Math.max(Math.min(num, Number.MAX_SAFE_INTEGER), Number.MIN_SAFE_INTEGER)
);
```

Examples:

```
let result1 = toSafeInteger('3.1');
let result2 = toSafeInteger('5.5');
console.log(result1); // 3
console.log(result2); // 6
```
