em values

Challenge Question: The h2's parent element has a font-size value of 16px. Use an em unit to give the h2 a font-size value equivalent to 53px. I see that as 53/16=3.31em But the challenge question was marked wrong. Can anybody explain?

53/16 = 3.3125. You have rounded this value. Include all digits and you should pass.
