c語言 函數的參數傳遞示例

C ++ restder()函數 (C++ remainder() function)

remainder() function is a library function of cmath header, it is used to calculate the remainder (IEC 60559), it accepts two parameters (numerator and denominator) and returns the remainder (floating-point) of numerator/denominator rounded to nearest,

restder()函數是cmath標頭的庫函數，用于計算余數(IEC 60559)，它接受兩個參數( 分子和分母 )，并返回四舍五入到最接近的分子 / 分母的余數(浮點數)，

remainder = numerator - rquot * denominator

Where, rquot is the value of numerator/denominator (rounded to the nearest integral value with halfway cases rounded toward the even number.

其中， rquot是分子 / 分母的值(四舍五入為最接近的整數值，中位數為四舍五入為偶數)。

Syntax of remainder() function:

restder()函數的語法：

C++11:

C ++ 11：

double remainder (double numer , double denom);float remainder (float numer , float denom); long double remainder (long double numer, long double denom);double remainder (Type1 numer , Type2 denom);

Parameter(s):

參數：

• numer, denom – represent the values of numerator and denominator.

  numer，denom –表示分子和分母的值。

Return value:

返回值：

It returns the remainder.

它返回余數。

Note:

注意：

• If the remainder is 0, then its sign is the same as the sign of numer.

  如果余數為0，則其符號與numer的符號相同。

• If the value of denom is 0, the result may either 0 or it may cause a domain error.

  如果denom的值為0，則結果可能為0或可能導致域錯誤。

Example:

例：

Input:double x = 15.46;double y = 12.56;Function call:remainder(x, y);Output:2.9

C ++代碼來演示restder()函數的示例 (C++ code to demonstrate the example of remainder() function)

// C++ code to demonstrate the example of // remainder() function#include <iostream> #include <cmath> using namespace std;// main() section int main() {double x;double y;x = 10;y = 2;cout << "remainder(" << x << "," << y << "): " << remainder(x, y);cout << endl;x = 5.3;y = 2;cout << "remainder(" << x << "," << y << "): " << remainder(x, y);cout << endl;x = 15.46;y = 12.56;cout << "remainder(" << x << "," << y << "): " << remainder(x, y);cout << endl;x = -10.2;y = 2;cout << "remainder(" << x << "," << y << "): " << remainder(x, y);cout << endl;return 0; }

Output

輸出量

remainder(10,2): 0 remainder(5.3,2): -0.7 remainder(15.46,12.56): 2.9 remainder(-10.2,2): -0.2
