Java BigDecimal intValue()方法与示例
BigDecimal類的intValue()方法 (BigDecimal Class intValue() method)
intValue() method is available in java.math package.
intValue()方法在java.math包中可用。
intValue() method is used to convert a BigDecimal to an integer and when the converted BigDecimal value is large enough to fit into an integer then in that case low order 32 bits are to be retrieved and the returned value is with opposite sign.
intValue()方法用于將BigDecimal轉換為整數,并且當轉換的BigDecimal值足夠大以適合整數時,在這種情況下,將檢索低階32位,并且返回的值帶有相反的符號。
intValue() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
intValue()方法是一個非靜態方法,只能通過類對象訪問,如果嘗試使用類名稱訪問該方法,則會收到錯誤消息。
intValue() method does not throw an exception at the time of converting BigDecimal to int.
在將BigDecimal轉換為int時, intValue()方法不會引發異常。
Syntax:
句法:
public int intValue();Parameter(s):
參數:
It does not accept any parameter.
它不接受任何參數。
Return value:
返回值:
The return type of this method is int, it gets the integer representation of this BigDecimal.
此方法的返回類型為int ,它獲取此BigDecimal的整數表示形式。
Example:
例:
// Java program to demonstrate the example // of int intValue() method of BigDecimalimport java.math.*;public class IntValueOfBD {public static void main(String args[]) {// Initialize two variables first is// of "double" and second is of "String"// typedouble val = 115.23;String str = "100";// Initialize two BigDecimal objects BigDecimal b_dec1 = new BigDecimal(val);BigDecimal b_dec2 = new BigDecimal(str);// convert this BigDecimal (b_dec1) into// an int, variable named i_convint i_conv = b_dec1.intValue();System.out.println("b_dec1.intValue(): " + i_conv);// convert this BigDecimal (b_dec2) into// an int, variable named i_convi_conv = b_dec2.intValue();System.out.println("b_dec2.intValue(): " + i_conv);} }Output
輸出量
b_dec1.intValue(): 115 b_dec2.intValue(): 100翻譯自: https://www.includehelp.com/java/bigdecimal-intvalue-method-with-example.aspx
