java.math.BigDecimal.unscaledValue() 返回一個BigInteger,其值是此BigDecimal的非標度值。 (Computes (this * 10this.scale()).)
以下是java.math.BigDecimal.unscaledValue()方法的宣告
public BigInteger unscaledValue()
NA
此方法返回BigDecimal的非標度值。
NA
下面的例子顯示math.BigDecimal.unscaledValue()方法的用法
package com.yiibai; import java.math.*; public class BigDecimalDemo { public static void main(String[] args) { // create 2 BigDecimal objects BigDecimal bg1, bg2; // create 2 BigInteger objects BigInteger bi1, bi2; bg1 = new BigDecimal("123.12"); bg2 = new BigDecimal("-245.03"); // assign unscaledValue of bg1,bg2 to bi1,bi2 bi1 = bg1.unscaledValue(); bi2 = bg2.unscaledValue(); String str1 = "The Unscaled Value of " + bg1 + " is " + bi1; String str2 = "The Unscaled Value of " + bg2 + " is " + bi2; // print bi1, bi2 values System.out.println( str1 ); System.out.println( str2 ); } }
讓我們編譯和執行上面的程式,這將產生以下結果:
The Unscaled Value of 123.12 is 12312 The Unscaled Value of -245.03 is -24503
