C++ cmath abs()用法及代码示例在本教程中,我们将借助示例了解 C++ abs() 函数。 C++ 中的abs() 函数返回参数的绝对值。它在cmath 头文件中定义。 在数学上,abs(num) = |num|。 示例 #include <iostream> #include <cmath> using namespace std; int main() { // get absolute value of -5.5 ...

Compute absolute value(function) 计算绝对值 floor Round down value(function) 四舍五入价值 fmod Compute remainder of division(function) 求模运算 C函数名: fmod 功能: 计算x对y的模, 即x/y的求余运算 (参见百科词条mod中的“求余函数” 条目),若y是0,则返回NaN。
abs() Return Value The abs() function returns: the absolute value of num i.e. |num| abs() Prototypes The prototypes of abs() as defined in the cmath header file are: double abs(double num); float abs(float num); long double abs(long double num); // for integral types double ...
