A simple addition in Java:
Float Value1 = 4.7, Value2 = 7.6
Addition Result = Value1 + Value2 = 12.299999 not 12.3 ?
Can someone help me to solve the problem without rounding the result?

What's wrong with the calculation?
A simple addition in Java:
Float Value1 = 4.7, Value2 = 7.6
Addition Result = Value1 + Value2 = 12.299999 not 12.3 ?
Can someone help me to solve the problem without rounding the result?
Re: What's wrong with the calculation?
Can you post the code that is the problem?
Do you understand about using floating point numbers and how they are stored in a computer's memory?

To get your desired results use the BigDecimal class with String values in its constructor:BigDecimal value1 = new BigDecimal("4.7");

btn_Result.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Value2 = Float.parseFloat(edt.getText().toString());
if (AddFlag == true){
edt.setText(Value1 + Value2 +"");
AddFlag=false;
}
if (SubFlag == true){
edt.setText(Value1 - Value2 +"");
SubFlag=false;
}
if (MulFlag == true){
edt.setText(Value1 * Value2 +"");
MulFlag=false;
}
if (DivFlag == true){
edt.setText(Value1 / Value2 +"");
DivFlag=false;
}
}
});

Did you try using the BigDecimal class?
Please edit your post and wrap your code with code tags:

to get highlighting and preserve formatting.
