Question

This has a potentially simple answer but I can’t figure it out –

double Result = 1 / 12;

returns 0, while

double Result2 = 24 / 12;

return 2

What’s going on and how can I fix it?

Answer 1

Try this:

double Result = 1 / (double)12;

or this:

double Result = 1 / 12D;

In C# (and also in a lot of other languages), integer division returns an integer. By casting one of the operands to double or explicitly declaring a literal double you can force the division expression to return a double and not truncate after the decimal place.
