C语言中的绝对值函数是abs(),它可以用于计算整数、浮点数或长整数的绝对值。调用abs()函数只需在括号内输入需要取绝对值的值即可。 示例代码如下: #include<stdio.h>#include<stdlib.h>intmain(){intnum =-10;intabsNum =abs(num);printf("The absolute value of %d is %d\n", num, absNum);floatf...
#include<stdio.h>#include<math.h>intmain(){doublenum =-1e-200;printf("The absolute value of %e is %e\n", num,fabs(num));return0; } 需要注意使用合适的浮点类型(如float或double)来满足精度要求。 五、绝对值的应用场景 1. 距离计算 绝对值常用于计算两个值之间的距离,例如: #include<stdio....
fabs()函数的用法：double fabs(double x)。其中参数x 是浮点值，这个函数返回x的绝对值。代码示例如下：int main (){ int a, b;a = 1234;b = -344;printf("The absolute value of %d is %lf", a, fabs(a));printf("The absolute value of %d is %lf", b, fabs(b));return(0)...
printf("The absolute value of %.2f is %.2f\n", num, abs_num);return 0;} ```在这个例子...
The absolute value of -3.14 is 3.14 在这个示例中，我们声明了一个双精度浮点数变量num，并将其初始化为-3.14。然后，我们使用fabs函数计算num的绝对值，并将结果存储在另一个双精度浮点数变量abs_num中。最后，我们使用printf函数打印出num和abs_num的值。需要注意的是，fabs函数只适用于float和double类型...

double absFloat = std::abs(floatingPointNumber); //输出结果 std::cout << "Absolute value of " << integerNumber << " is: " << absInteger << std::endl; std::cout << "Absolute value of " << floatingPointNumber << " is: " << absFloat << std::endl; return 0; } 请注意,在...
float c = 7.8; float d = 4.1; printf("Absolute values of %.1f, %.1f, %.1f, %.1f are: %.1f, %.1f, %.1f, %.1f ", a, b, c, d, fabs(a), fabs(b), fabs(c), fabs(d)); return 0; } 输出结果: Absolute values of 5.5, 3.2, 7.8, 4.1 are: 5.5, 3.2, 7.8, 4.1 ...
floata; a=fabs(x); printf("The absolute value of x is: %f\n",a); } To compile our code, we need to run the following line from the command console, specifying the path of the “main.c” file and the output which, in this case, gives our application the name, “app_fabs1”...
