A function to return a sign

Question

I know this will really turn out to be simple, but my brain is just not working. I need a function in C# that will return -1 if the integer passed to the function has a nega

Answer 1

This is already in the framework. Just use Math.Sign...

int sign = Math.Sign(-82); // Should return -1
int sign2 = Math.Sign(197); // Should return 1
int sign3 = Math.Sign(0);   // Should return 0

In addition, it will work with:

int sign4 = Math.Sign(-5.2); // Double value, returns -1
int sign5 = Math.Sign(0.0m); // Decimal, returns 0
// ....
