Check the methods on the Math class. Something like Math.round(value1 /
10.9375) and so on.

I am currently working on an app that takes 4 user input values and
puts them through the following equation and gives an answer. The only
thing is that it wont work.
the equation is as follows.
answer = max { round ( (value1 / 10.9375)+(value2 / 9.2105)+(value3 /
3.889)-(value4 / 12.5) ) ,0 }
so far i have the following
package com.android.app;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
public class Equation extends Activity {
Button submit;
EditText val1,val2,val3,val4r;
TextView answer;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
/* First Tab Content */
setContentView(R.layout.equation);
val1 = (EditText) findViewById(R.id.value1);
val2 = (EditText) findViewById(R.id.value2);
val3 = (EditText) findViewById(R.id.value3);
val4 = (EditText) findViewById(R.id.value4);
submit = (Button) findViewById(R.id.submit);
answer = (TextView) findViewById(R.id.answer);
submit.setOnClickListener(new clicker());
}
class clicker implements Button.OnClickListener
{
public void onClick(View v)
{
String a,b,c,d;
Integer Int;
a = val1.getText().toString();
b = val2.getText().toString();
c = val3.getText().toString();
d = val4.getText().toString();
Int = max { round ( (a / 10.9375)+(b / 9.2105)+(c / 3.889)-
(d / 12.5) ) ,0 }
points.setText(Int.toString());
}
}
}
so... thats what i have, can you help?
