a very very beginner question

[bbcc]

Greetings,

I have a very very beginner question. I am terying to understand a code and sometimes I doubt about a beginner point !!!

edepSum *=x;
edepSum2 *= x;
edepSum2 -= edepSum*edepSum;

The 1st line says that the previous value of edepSum is multiplied by x and the new value is stored in edepSum.

The second one implies the same thing.

The third line implies that the previous value of edepSum2 is subtracted from edepSum*edepSum and the subtraction result is stored in edepSum2.

Could you please tell me if I am in the right track ???

Thank you in advance

You are correct, that's exactly what that code does. Except, as Xander pointed out, you have the third part backwards. It subtracts edepSum*edepSum from the original value of edepSum2.

The syntax you posted is equvialent to:

edepSum = edepSum * x;
edepSum2 = edepSum2 * x;
edepSum2 = edepSum2 - edepSum * edepSum;

So yes, you are right.

edit: Xander314 is right, fixed my syntax

The third line implies that the previous value of edepSum2 is subtracted from edepSum*edepSum and the subtraction result is stored in edepSum2.

Surely it should be "the value of edepSum*edepSum is subtracted from the previous value of edepSum2 and the subtraction result is stored in edebSum2", and not the other way round. Perhaps this was just a typo?
