printf("The absolute value of %.2f is %.2f\n", y, result_y); return 0; } 这个“fabs”函数就像是“abs”函数的大哥哥,专门负责浮点型数据的绝对值计算,而且它计算得可精准啦。 3.自己编写函数求绝对值(不使用库函数) 对于整型数据,我们也可以自己写一个函数来求绝对值。比如说: c include <stdio...
int abs_x = abs(x);调用自定义的 abs() 函数计算 x 的绝对值 printf("The absolute value of %d is %d.\n", x, abs_x);输出 x 和其绝对值 return 运算结果：The absolute value of -10 is 10.

How to Find the Absolute Value of a Number with Decimal Fractions Using the Fabs() Function in the C Language In this example, we will show you how to determine the absolute value of a variable of the Float type that contains a decimal value. The first step is to create our “main.c...
在编写程序时有时需要得到绝对值来进行判断之类的步骤,下面我用两种方法来展示下如何取绝对值。...函数法下面来演示使整型变量取绝对值的方法 1.创建函数 代码如下: int absolute(int number)//声明一个返回值为整形的函数absolute,形参为整型变量number...,将absolute()函数和main()函数中变量前的int 变为float...

the fixed utility theory assumes that the rational decision-maker assigns a subjective absolute value (utility) to any action or option. Moreover, these utilities are context-independent such that options can be hierarchically ranked. As a consequence, a rational decision-maker should be consistent ...
