You're using sprintf() with the float correctly, you're just missing how it's rounding. (10.03 * 19.6) / 100 = 1.96588 (rounded to 1.97) ((10.03 * 19.6) / 100) * 2 = 3.93176 (rounded to 3.93) If you want it to come out to an even number with the VAT added, simply round the amount first, then multiply it. -- </Daniel P.
