tohexstring方法_Java Float类toHexString()方法的示例
tohexstring方法
浮動類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()方法用于表示單精度浮點類型的給定參數[value]的十六進制字符串。
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()方法是一個靜態方法,也可以使用類名進行訪問,并且如果我們嘗試使用類對象訪問該方法,那么我們也不會收到錯誤。
toHexString() method does not throw an exception at the time of conversion from float to Hexadecimal string.
從float轉換為16進制字符串時, toHexString()方法不會引發異常。
Syntax:
句法:
public static String toHexString (float value);Parameter(s):
參數:
float value – represents the float value to be converted.
浮點值 –表示要轉換的浮點值。
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.
此方法的返回類型為String ,它返回給定參數的代表十六進制值的十六進制字符串。
Example:
例:
// Java program to demonstrate the example // of toHexString(float value) method of Float classpublic class ToHexStringOfFloatClass {public static void main(String[] args) {// Variables initializationfloat f1 = 10.0f;float f2 = 20.0f;float f3 = 30.0f;float f4 = Float.MAX_VALUE;float f5 = Float.MIN_VALUE;// Float instance creationFloat value = new Float(f1);// It represents hexadecimal string of the given// float type f2 argumentString s = value.toHexString(f2);// Display Hexadecimal String RepresentationSystem.out.println("value.toHexString(f2): " + s);// It represents hexadecimal string of the given// float type f3 arguments = value.toHexString(f3);// Display Hexadecimal String RepresentationSystem.out.println("value.toHexString(f3): " + s);// It represents hexadecimal string of the given// float type f4 arguments = value.toHexString(f4);// Display Hexadecimal String RepresentationSystem.out.println("value.toHexString(f4): " + s);// It represents hexadecimal string of the given// float type f5 arguments = value.toHexString(f5);// Display Hexadecimal String RepresentationSystem.out.println("value.toHexString(f5): " + s);} }Output
輸出量
value.toHexString(f2): 0x1.4p4 value.toHexString(f3): 0x1.ep4 value.toHexString(f4): 0x1.fffffep127 value.toHexString(f5): 0x0.000002p-126翻譯自: https://www.includehelp.com/java/float-class-tohexstring-method-with-example.aspx
