converting decimal to int in c#

Question

why percentage returns 0 when rate = 0.085 for example ?

int percentage = (int)rate*100;

Answer 1

The cast operation is applied before the multiplication. Try:

int percentage = (int)(rate*100);

Edit: Here's the C# guide on order of operator evaluation.

Answer 2

It returns 0 because of order of operations. rate is cast as an integer prior to multiplying.

You need an extra set of parentheses to make this work.

int percentage = (int)(rate*100);

Answer 3

Try:

int percentage = (int)(rate * 100);
