## is-safe-integer-x

Determine whether the passed value is a safe integer.



### `module.exports(value)` ⇒ boolean ⏏

This method determines whether the passed value is a safe integer.

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.

**Kind**: Exported function  

**Returns**: boolean - A Boolean indicating whether or not the given value is a

safe integer.

| Param | Type            | Description                                      |

| ----- | --------------- | ------------------------------------------------ |

| value | \* | The value to be tested for being a safe integer. |

**Example**

```js

import isSafeInteger from 'is-safe-integer-x';

console.log(isSafeInteger(0)); // true

console.log(isSafeInteger(1)); // true

console.log(isSafeInteger(-100000)); // true

console.log(isSafeInteger(Math.pow(2, 53))); // false

console.log(isSafeInteger(0.1)); // false

console.log(isSafeInteger(Math.PI)); // false

console.log(isSafeInteger(NaN)); // false

console.log(isSafeInteger(Infinity)); // false

console.log(isSafeInteger(-Infinity)); // false

console.log(isSafeInteger('10')); // false

console.log(isSafeInteger(true)); // false

console.log(isSafeInteger(false)); // false

console.log(isSafeInteger([1])); // false
