ArmにあるというJavaScript専用命令とは何か、あるいは浮動小数点数を整数に変換する方法について - Qiita
元の値の絶対値が大きすぎる場合や、無限大、NaNの場合は、 6.3.1.4: 表現できない場合はundefined behavior。 Annex F.4: 表現できない場合はinvalid例外が発生して、値はunspecified。 とされています。 これ以外の浮動小数点数→整数型の変換方法には (l)lrint や (l)lround 関数などがあります。 Java 基本的に0方向への丸め（切り捨て）で計算されますが、コーナーケースについても言語仕様で定めています。 NaN：0を返す 結果が表現できないもしくは無限大の場合：符号に応じて最大値または最小値が返る。 参照： 5.1.3.
