/*! 🔢 IntegerBox - 整数計算Box
*
* ## 📝
* 64Box
* JavaScript Number型のように直感的な数値操作が可能
*
* ## 🛠
* - `toString()` -
* - `add(other)` - (: +)
* - `subtract(other)` - (: -)
* - `multiply(other)` - (: *)
* - `divide(other)` - (: /)
* - `modulo(other)` - (: %)
* - `equals(other)` - (: ==)
* - `abs()` -
* - `min(other)` -
* - `max(other)` -
*
* ## 💡 使
* ```nyash
* local num, result, text
* num = 42
*
* result = num + 8 // 50
* result = num * 2 // 84
* result = num / 3 // 14 (整数除算)
* text = num.toString() // "42"
*
* // メソッド呼び出し形式も可能
* result = num.add(10) // 52
* result = num.multiply(3) // 126
* ```
*
* ##
* -
* - i64の動作に従う
* -
