無限大について全力で考えてみる

InfinityCheck_06.cs

	void FourArithmeticInfinity(){
		// 足し算
		// 無限大に数値を足す
		float additionToInf = Mathf.Infinity + 1.0e+38f;
		Debug.Log("additionToInf : " + additionToInf);

		// 無限大に無限大を足す
		float additionInfToInf = Mathf.Infinity + Mathf.Infinity;
		Debug.Log("additionInfToInf : " + additionInfToInf);


		// 引き算
		// 無限大から数値を引く
		float subtractionFromInf = Mathf.Infinity - 1.0e+38f;

		// 無限大から無限大を引く
		float subtractionInfFromInf = Mathf.Infinity - Mathf.Infinity;
		Debug.Log("subtractionInfFromInf : " + subtractionInfFromInf);


		// 掛け算
		// 無限大に数値を掛ける
		float multiplicationInf = Mathf.Infinity * 1.0e+38f;

		// 割り算

		// 無限大を無限大で割る
