Example: 例 Input:
float val110.00f;
float val210.23f;
float val310.50f;
float val410.65f;
Output:
After round val110
After round val210
After round val311
After round val411
Program: 程序 #include stdio.h
//Macro
#define round(x) ((x)0?(long)((x)0.5):(long)((x)-0.5))
//Main code
int main(void)
{
float val110.00f;
float val210.23f;
float val310.50f;
float val410.65f;
printf(After round val1%d\n,round(val1));
printf(After round val2%d\n,round(val2));
printf(After round val3%d\n,round(val3));
printf(After round val4%d\n,round(val4));
return 0;
}
Output 输出量 After round val110
After round val210
After round val311
After round val411
