Why the sum is different to real data?

Hi I have a doubt about, how matlab SUM values, maybe is quite easy for you answer this, but I have an issue based on the following: 1-I have real data about Power Consumption in a Buiding and in average that facility consumes 1740.48 e3 kW per day 2-I load the above data in my simulation based in Photovoltaic generation and I ran it for a day (3600seconds*24hours) 3-I extract the IL(intensity consumed by load) and VL (voltage on the load) from blocks "to file", I apply a simply multiplication 4-In order to find out the consumption during that period of time (24 hours), I apply the function "sum(PL)" and I receive a very large value, that is very uncomprehensible because is around of GW, when it should be kW per day. For me is hard to accept that value, that's why I give up to find an answer to that, please give me a hand in order to get the right value.

Also, can you attach a sample MATLAB script that shows the issue you are facing?

The results are not "bad", but only unexpected. You can be sure, that Matlab calculates the sum exactly. This means, that your expectations do not match the data. Did you see KL's comment?
