# number-operator
> Because JS uses the IEEE 754 double version (64-bit), and it has this problem as long as it uses the IEEE 754 language. So when we calculate the number operation, there will be a precision error


# Installation

```bash
npm install -D number-operator
```

# Usage
> Normal environment computing
