/*! 🔢 IntegerBox - 整数計算Box
|
||
*
|
||
* ## 📝 概要
|
||
* 64ビット符号付き整数を扱うためのBox。
|
||
* JavaScript Number型のように直感的な数値操作が可能。
|
||
*
|
||
* ## 🛠️ 利用可能メソッド
|
||
* - `toString()` - 文字列変換
|
||
* - `add(other)` - 加算 (演算子: +)
|
||
* - `subtract(other)` - 減算 (演算子: -)
|
||
* - `multiply(other)` - 乗算 (演算子: *)
|
||
* - `divide(other)` - 除算 (演算子: /)
|
||
* - `modulo(other)` - 余り計算 (演算子: %)
|
||
* - `equals(other)` - 等価比較 (演算子: ==)
|
||
* - `abs()` - 絶対値
|
||
* - `min(other)` - 最小値
|
||
* - `max(other)` - 最大値
|
||
*
|
||
* ## 💡 使用例
|
||
* ```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
|
||
* ```
|
||
*
|
||
* ## ⚠️ 注意
|
||
* - ゼロ除算は実行時エラー
|
||
* - オーバーフロー時は標準i64の動作に従う
|
||
* - 小数点以下は切り捨て(整数除算)
