Here's one more question:
Before I knew that opEquals existed, I tried overloading the
equality expressions (== and !=) in opBinary using the code
below. It worked. Why would the overloaded opBinary version get
called if the equality expressions are held in opEquals? I'm just
interested in kn
And thanks for that pointer, too, H.S.
Wow! You guys are fast and helpful! Thank you Jonathan and Ali! I
already got it to work, and Ali, your book is great! I've read
about the first 150 pages. I'll check out those operator
overloading chapters for sure.

So, this is Rat's opCmp, correct? If it's a struct, it makes no sense for it
to take an Object. Object is the base class for all classes and has nothing to
do with structs. o
Thanks for the quick response!
Here is the initialization code for my Rat struct. I created a
GCD function that I've tested to work fine:
import std.stdio, std.exception;
struct Rat {
private long n; //Numerator
private long d; //Denominator
Also…Rat is a struct, not a class. Herein might lie the problem.

I'm trying to implement rational numbers with fully functioning
comparison operators, but I can't seem to figure out why I'm
getting this error and any help would be appreciated:
Error: cannot cast from object.Object to Rat
The code I have is as follows:
