Some C Help please!!

Ok i have this problem
double answer= 4-2.7*(5 % (int)5.2);

My questions is what role does % play, and also what role does int play in the brackets.

I get confused, since this is seen as a double. But then you have an int

I know the answer is 4.000000

but how and most importantly why?

Any help greatly appreciated.

double answer= 4-2.7*(5 % (int)5.2);

Never mind I figured out hat 5%(int)5.2) you divide and are looking for the remainder which in this case is 0.
