原型：
double abs (double x);
float abs (float x);
long double abs (long double x);
double abs (T x); // additional overloads for integral types
代码：
// cmath‘s abs example #include <iostream> // std::cout #include <cmath> // std::abs int main () { std::cout << "abs (3.1416) = " << std::abs (3.1416) << ‘\n‘; std::cout << "abs (-10.6) = " << std::abs (-10.6) << ‘\n‘; return 0; }
