I had to show my apprentice today how to use the modulus operator, as he just didn't get it.

But before that I had to explain how to divide integers leaving a quotient and remainder. He didn't get that either.

"Ok, so tell me the remainder of one divided by two..."
(several seconds pause)
"That's a bit hard."

I ended up drawing diagrams and using coins to explain how to do division. Just what are they teaching them these days??

Also, he invented the "<=>" operator the other day, meaning less than or equal to or greater than. I lol'd.

Actually Ruby has a <=> operator. It's pronounced spaceship. You implement it if you want your class to be comparable.

It's just a fancy strcmp

Its function is very different from the one explained. It does basically the same thing as the Haskell compare.

Is that even relevant to the topic, or is it just your way of saying "Ive read SICP"?

He obviously has hidden genius, <=> is a winner. You should apologise for laughing at him.

<=> sounds like the type of operation PHP would support to add to the existing empty, isset, is_null, ==, ===, etc. insanity.

Name: Anonymous 2007-07-16 6:32 ID:klpS6Xej

The only insane one is empty(), because it's retarded.

and let's not forget (bool), == 1, == "" and array_key_exists.

Effective way of moving not-numbers to the beginning of the list

[ <=> ] sort
Sorts a sequence of objects in natural order using the <=> word.

the <=> word:

Compares two objects using an intrinsic partial order, for example, the natural order for real numbers and lexicographic order for strings.
...
The default implementation treats the two objects as sequences, and recursively compares their elements. So no extra work is required to compare sequences lexicographically.
