Java中的 StrictMath IEEEremainder() 方法
Java.lang.StrictMath.IEEEremainder() 是 StrictMath 类的内置方法,用于对 IEEE 754 标准规定的给定两个参数执行余数运算。余数值在数学上等于 , 其中rem是最接近商的精确数学值的数学整数 ,并且当两个数学整数同样接近 , n 为偶数。它产生了两个特殊的结果:
- 当余数为零时,其符号与第一个参数的符号相同。
- 当任一参数为 NaN,或num1为无穷大,或num2为正零或负零时,它返回 NaN。
- 当num1为有限且num2为无限时,结果与num1相同。
句法:
public static double IEEEremainder(double num1, double num2)
参数:该方法接受两个参数:
- num1:这是双精度类型,即被除数。
- num2这是双精度型的 als,它是除数。
返回值:该方法返回 num1 除以 num2 的余数。
例子 :
Input:
num1 = 100.61d
num2 = 5.32d
Output: -0.47000000000000597
下面的程序说明了Java.lang.StrictMath.IEEEremainder() 方法:
方案一:
java
// Java program to illustrate the
// Java.lang.StrictMath.IEEEremainder()
import java.lang.*;
public class Geeks {
public static void main(String[] args)
{
double num1 = 5651.51d, num2 = 61.79d;
// It returns the remainder value
double remain_val = StrictMath.IEEEremainder(num1, num2);
System.out.println("Remainder value of "+num1+" & "+num2
+" = " + remain_val);
}
}
java
// Java program to illustrate the
// Java.lang.StrictMath.IEEEremainder()
import java.lang.*;
public class Geeks {
public static void main(String[] args)
{
/* Here num1 is finite and num2 is infinite so
the result is the same as the num1 */
double num1 = 70.55d, num2 = (1.0) / (0.0);
double remain_val = StrictMath.IEEEremainder(num1, num2);
System.out.println("Remainder value of "+num1+" & "+num2
+" = " + remain_val);
}
}
输出:
Remainder value of 5651.51 & 61.79 = 28.620000000000296
方案二:
Java
// Java program to illustrate the
// Java.lang.StrictMath.IEEEremainder()
import java.lang.*;
public class Geeks {
public static void main(String[] args)
{
/* Here num1 is finite and num2 is infinite so
the result is the same as the num1 */
double num1 = 70.55d, num2 = (1.0) / (0.0);
double remain_val = StrictMath.IEEEremainder(num1, num2);
System.out.println("Remainder value of "+num1+" & "+num2
+" = " + remain_val);
}
}
输出:
Remainder value is = 70.55
