subtangent，英語單詞，主要用作名詞，作名詞時譯為“次切距”。
次導數（subderivative）、次微分（subdifferential）、次切線（subtangent lines）和次梯度（subgradient）的概念出現在凸分析，也就是凸函式的研究中。 要注意的是，次切線（subtangent lines）和次切距（subtangent）是不同的。定義 設 是一個實變數凸函式，定義在實數軸上的開區間內。這種函式不一定是處處可導的，...
返回一個 Double，指定一個數的反正切值。必要的 number 參數是一個 Double或任何有效的數值表達式。Atn 函式的參數值 （number） 為直角三角形兩邊的比值並返回以弧度為單位的角。這個比值是角的對邊長度除以角的鄰邊長度之商。值的範圍在 -pi/2 和 pi/2 弧度之間。為了將角度轉換為弧度，請將角度乘以 pi/...

求y/x的arctangent值。● rand()：得出一個隨機值。此值平均分布在0和l之間。這個值不會是0和1。● srand(x)：以X為種子產生隨機數。設定產生隨機值的開始點或seed為x。如果在第二次用戶設定相同的seed值，用戶將再度得到相同序列的隨機值。如果省略參數x，例如srand()，則當前的日期、時間會被當成seed。
