Actually programmers use the symbols far more frequently than the numbers. The number row on Programmer Dvorak is, from left-to-right,

  & [ { } ( = * ) + ] ! #

Looks really weird at first glance! but if you try it out, [square brackets] and (parens) are symmetrical fingers on opposing hands. By hand, [] is the ring fingers (2,0 on a qwerty). {} is (3,4 on the left-hand) and () is 5,8 aka your pointing fingers, left hand then right.

Having the luxury of the parens and frequent symbols (especially if you code Clojure or a Lisp) on the tippy-top row is awesome.

Plus, the numbers are also split by hand!

From middle-going-out:

Left hand: 91357 Right hand: 02468

Which lets you type numbers without looking for them by eye :)

What is the advantage of this order vs. numerical order? If I'm reading your post correctly the numbers are arranged 7531902468 on the keyboard, with maybe a space in the middle? Is there some mathematical property where odd and even numbers are more likely to alternate than for odds or evens to be found side by side? Maybe 0 is more likely to appear so they want it on an index finger? It just seems unlikely that the next most common digit is 9, unless this was developed by people who set prices on items.

Very simply: if it's an even number, it's your left hand. If it's an odd number, it's your right hand. If you want to type a number like 2,467,333 you can do it without looking for the numbers. On qwerty I tend to "lose my footing" when it comes to typing numbers out. But if it's a 2 on programmer-dvorak, it's right hand, index finger. 2468 is each of your four digits, in order. and 1357 is the other hand's digits. However, I hold left-shift to access the numbers which means my pinky is unavailable for the left numerical ascension, so I tend to do 1 and 3 with my index, and 5 with middle, and 7 with ring. Nine [9] and Zero [0] are "stretch" numbers in the middle: 9 and 0 are reached via one's index fingers going diagonally toward the middle of the tippy-top row.

tl;dr: right hand even,, left hand odd,,, increasing from index to pinky. "Look ma, no eyes!"

You don't need a special keyboard layout for that. Any layout at all has the same feature.

Why not use the numpad?

What numpad :)?

The only possible answer to that is "get a real keyboard".

That doesn't suit my lifestyle - never going to drag a keyboard to a coffee shop, for example. Also I would gently challenge the notion that people are able to type numbers without looking accurately on a standard keyboard. Can you type 15,483,523 on the first try with no errors? Because when I try on qwerty mode I get 26,584,634 lol.
