ArrayUtil doueleBitCount about opslabjutil

[kimmil]

这样就可以了
public static int doueleBitCount(double dd)
{
String temp = String.valueOf(dd);
BigDecimal bd = new BigDecimal(temp);
String str = bd.toPlainString();
System.out.println(str);
int i = str.indexOf(".");
if (i > -1)
{
return str.length() - i - 1;
}
return 0;

}

public static void main(String[] args)
{
    Double a = 3.0123456789E9;
    System.out.println(a);
    System.out.println(doueleBitCount(a));
}
