Double calculation always result in 32.00000

Question

I was trying to convert Centrigrade Temperatures into Fahrenheit. The formula is tempc *(9.0/5.0)+32

Tempc is a double value. But whatever I put in for tempc the result is always the same, namely 32 because the multiplication part evaluates to 0. Why?
Any help?

Answer 1

I'm getting the right answer :
#include <iostream>
using namespace std;

int main() {
double temp = 37 *(9.0/5.0)+32;
cout<<temp;
return 0;
}

Answer 2

Well that's strange
