public class test{
public static void main(
String args[] ){
float A = 1.0F / 3.0F ;
double d=1.0 / 3.0 ;
1. System.out.println("d="+d);
2 System.out.println("before cast A= "+A);
//After casting
3 System.out.println("after cast A="+(double)A);
4 System.out.println("AA="+A*7.0);
5 System.out.println("AAA="+A*7.0F);
6 if( ( A * 7.0f == 1.0F )) System.out.println( "Equal" );
else System.out.println( "Not Equal" );
}
}
At line 3 when we type cast float to double ,few additional
digits are added to the result.See the diff in result at line 2 And line 3.But atually i feel this should not happen .Please anybody give me reason for that.
