/*! ✅ BoolBox - 真偽値Box
|
||
*
|
||
* ## 📝 概要
|
||
* true/false値を扱うためのBox。
|
||
* JavaScript Boolean型のように直感的な論理演算が可能。
|
||
*
|
||
* ## 🛠️ 利用可能メソッド
|
||
* - `toString()` - 文字列変換 ("true" / "false")
|
||
* - `not()` - 論理NOT (演算子: not)
|
||
* - `and(other)` - 論理AND (演算子: and)
|
||
* - `or(other)` - 論理OR (演算子: or)
|
||
* - `equals(other)` - 等価比較 (演算子: ==)
|
||
*
|
||
* ## 💡 使用例
|
||
* ```nyash
|
||
* local flag, result, text
|
||
* flag = true
|
||
*
|
||
* result = not flag // false
|
||
* result = flag and true // true
|
||
* result = flag or false // true
|
||
* text = flag.toString() // "true"
|
||
*
|
||
* // 条件分岐での利用
|
||
* if (flag) {
|
||
* print("Flag is true!")
|
||
* }
|
||
* ```
|
||
*
|
||
* ## 🔄 型変換
|
||
* - 数値への変換: true → 1, false → 0
|
||
* - 文字列への変換: "true" / "false"
|
||
* - 空文字・null・0は false として扱われる
|
||
*
|
||
* ## ⚡ 論理演算子実装済み
|
||
* - `not condition` - NOT演算子
|
||
* - `a and b` - AND演算子
|
||
* - `a or b` - OR演算子
