Question

I have the following code :

double a = 8/ 3;
Response.Write(a);

It returns the value 2. Why? I need at least one decimal digit. Something like 2.6, or 2.66. How can I get such results?

Answer 1

Try

double a = 8/3.0d;

or

double a = 8.0d/3;

to get a precise answer.

Since in expression a = 8/3 both the operands are int so the result is int irrespective of the fact that it is being stored in a double. The results are always in the higher data type of operands

EDIT

To answer

8 and 3 are get from variable. Can I do a sort of cast?

In case the values are coming from a variable you can cast one of the operands into double like:

int b = 8;
int c = 3;
double a = ((double) b) /c;
