tohexstring方法

浮动类toHexString()方法 (Float class toHexString() method)

• toHexString() method is available in java.lang package.

  toHexString()方法在java.lang包中可用。

• toHexString() method is used to represent a hexadecimal string of the given parameter [value] of single-precision floating-point type.

  toHexString()方法用于表示单精度浮点类型的给定参数[value]的十六进制字符串。

• toHexString() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.

  toHexString()方法是一个静态方法，也可以使用类名进行访问，并且如果我们尝试使用类对象访问该方法，那么我们也不会收到错误。

• toHexString() method does not throw an exception at the time of conversion from float to Hexadecimal string.

  从float转换为16进制字符串时， toHexString()方法不会引发异常。

Syntax:

句法：

    public static String toHexString (float value);

Parameter(s):

参数：

• float value – represents the float value to be converted.

  浮点值 –表示要转换的浮点值。

Return value:

返回值：

The return type of this method is String, it returns the hexadecimal string of the given parameter that represent the float value.

此方法的返回类型为String ，它返回给定参数的代表十六进制值的十六进制字符串。

Example:

例：

// Java program to demonstrate the example 
// of toHexString(float value) method of Float class
public class ToHexStringOfFloatClass {
public static void main(String[] args) {
// Variables initialization
float f1 = 10.0f;
float f2 = 20.0f;
float f3 = 30.0f;
float f4 = Float.MAX_VALUE;
float f5 = Float.MIN_VALUE;
// Float instance creation
Float value = new Float(f1);
// It represents hexadecimal string of the given
// float type f2 argument
String s = value.toHexString(f2);
// Display Hexadecimal String Representation
System.out.println("value.toHexString(f2): " + s);
// It represents hexadecimal string of the given
// float type f3 argument
s = value.toHexString(f3);
// Display Hexadecimal String Representation
System.out.println("value.toHexString(f3): " + s);
// It represents hexadecimal string of the given
// float type f4 argument
s = value.toHexString(f4);
// Display Hexadecimal String Representation
System.out.println("value.toHexString(f4): " + s);
// It represents hexadecimal string of the given
// float type f5 argument
s = value.toHexString(f5);
// Display Hexadecimal String Representation
System.out.println("value.toHexString(f5): " + s);
}
}

Output

输出量

value.toHexString(f2): 0x1.4p4
value.toHexString(f3): 0x1.ep4
value.toHexString(f4): 0x1.fffffep127
value.toHexString(f5): 0x0.000002p-126
