Yes, you CAN have "2" as an answer - but only if the input data, after normalisation, comes to 2. Go read the tutorial I linked to in my earlier email and you'll understand. Now, the other thing is to be able to read the output correctly. I'll lay odds that you did NOT get "200M", you'll have got "200m". 200m is 200 Million, or 200,000,000 2m is 200 milli, or 0.2 That is a very important distinction ! BTW - these are standard SI measures. 2.0000000000e-01 is scientific notation, it means 2.0000000000 time 10^-1 (that's ten to the power of -1). 10^-1 is 0.1, so 2 x 0.1 is 0.2 The value 2 would be written as 2.0000000000e-00 The easy way to convert is to simply move the decimal point right by the number of places indicated in the exponent. Moving right by -1 is the same as moving 1 left, so 2.00 becomes 0.200.
