C trunc 函数

C trunc 函数是数学函数之一,用于返回给定数字或指定表达式的截断值。此编程中的 truncate 函数的语法为:

double trunc(double value);

trunc 函数示例

math trunc 函数允许您找到给定数字的截断值。在此程序中,我们将查找不同数字的截断值并显示输出。

#include <stdio.h>
#include <math.h>

int main()
{
    printf("\n The Truncated Value of 0.75    = %.2f ", trunc(0.75));
    printf("\n The Truncated Value of 15.25   = %.2f ", trunc(15.25));
    printf("\n The Truncated Value of 152.50  = %.2f ", trunc(152.50));
    
    printf("\n The Truncated Value of -14.36  = %.2f ", trunc(-14.36));
    printf("\n The Truncated Value of -26.82  = %.2f ", trunc(-26.82));
    printf("\n The Truncated Value of -90.55  = %.2f \n", trunc(-90.55));
    
    return 0;
}

C truncate 示例 2

在此 字符串函数 示例中,我们允许用户输入他们的值。接下来,此 程序 使用此函数来截断用户指定的值。

#include <stdio.h>
#include <math.h> 

int main()
{
    float number, trunc_Value;
    
    printf(" Please Enter any Numeric to Round :  ");
    scanf("%f", &number);
    
    trunc_Value = trunc(number);
    
    printf("\n The Result of %.2f = %.4f \n", number, trunc_Value);
    
    return 0;
}
 Please Enter any Numeric to Round :  234.589

 The Result of 234.59 = 234.0000
