## Usage

```js

import isPositiveInt from 'is-positive-int';

// Test cases

// Valid positive values

isPositiveInt(0);                           // true

isPositiveInt(1);                           // true

isPositiveInt(5034);                        // true

isPositiveInt(Math.pow(2, 53) - 1);         // true

isPositiveInt(Number.MAX_SAFE_INTEGER);     // true

isPositiveInt(1.0);                         // true

isPositiveInt(5e2);                         // true, 500 in exponential notation

isPositiveInt(9.007199254740991e15);        // true, Number.MAX_SAFE_INTEGER.toExponential()

// Invalid values

isPositiveInt(-5034);                       // false

isPositiveInt(-Math.pow(2, 53) - 1);        // false

isPositiveInt(-Number.MAX_SAFE_INTEGER);    // false

isPositiveInt(Number.MIN_SAFE_INTEGER);     // false

isPositiveInt(1.1);                         // false
