The code below works ok and displays result (mDisplayNominalEff) to screen but I want to round the result to 3 places.
I assume that I need to parse string to double.
Any ideas on how to do this?
String mDisplayNominalEff = ("" + (myDiameter - (myPitch * 0.649519)));
TextView displayNominalEff = (TextView) findViewById(R.id.nominalEffTV);
displayNominalEff.setText(mDisplayNominalEff);
