Error CS0161-not all code paths return a value

[rdaoogle]

private double calculateRange(double High1, double High2, double Low1, double Low2)
{

if( Low1<Low2)
return High1-Low1;
if( Low2<Low1)
return High1-Low2;
if( High1<High2)
return High2-Low1;
if( High2<High1)
return High1-Low1;

}

When I try to compile it gives me 2 errors "cso161 not all code paths return a value" pointing me to the parts in bold. Could somebody please explain what that means and how to fix it?

Hello Rdaoogle,

Thank you for your post.

When doing a method that returns a value you need to have at least one of the conditions be true.

Since, all of these conditions could in theory be false, there is nothing to return a value.

You can out a ELSE statement at the end to return a value to show that none of the conditions were met.

Let me know if I can be of further assistance.

You need a final return directive/value if all your if blocks fall through, using either an else block or an unconditional return.

yep, that fixed it.
Thank you both!
