The fix was easy, just move the code out of the numberic literal parsing routine rvalue() to rfactor() where the unary + and - occur, as well as handing subexpressions. But the fix lead to another issue?how to handle a sequence like -3!. Should it error out since negative values aren't defined for factorial? Or should it apply the factorial to ?3? and then the unary minus sign?

I asked the question over on Lobters and a very loose consensus seemed to be that factorial has a higher precedence than unary minus. I also threw -3! at Wolfram Alpha (that I forgot existed until I started doing some web searches on the question) and it also handled factorial before unary minus.

So that's what I went with. From what little I found on this topic, it seems that -3! should indeed return -6 as an answer. It also seems to be the mathematical convention that -3² should return -9 and not 9 (which is that my assembler returns, as well as Microsoft Excel). Fixing that issue would require a rewrite of the expression parser. The Shunting Yard algorithm I use to handle precedence doesn't handle unary operators all that well.

Sigh.

Sigh.

Nor so quickly.

Geeze.

We're home now.

I still have a few observations about the habilitation center.

1. Everyday I was there (and I was there every day) in the main hall I would see a gentleman in a wheel chair. He was always wearing a straw hat so he was recognizable, and every time he saw me, he would salute me and thank me for visiting. I would always wave back and say, "you're welcome!" I never noticed anyone seemingly visiting him though.
2. Another gentleman I would see from time to time was a double amputee (legs, just above the knees). One day as I was aproaching the vending machines in the main hall, he wheeled over to me and handed me $5 to get him a drink. He had a very thick accent, and it was hard to see where he was pointing to, and yet, I still managed to not give him what he wanted. Twice. I still feel very bad about that over two weeks later.
3. Bunny's roommate was a frail old lady in her 90s, maybe weighing 90 pounds (40kg) soaking wet. She had incredible lungs though?every time she had her blood pressure taken, it sounded like she was being murdered, and it was loud enough that I'm sure everyone in the facility could hear her, even on the second floor. It was both literally and figuratively painful to hear.
4. The kitchen staff would gladly give out a second helping if you asked. Did I mention the food was quite good?
5. Technically, to exit the building, you have to ask a staff member to open the front door. I was there often enough to see how they would open the front door, so I didn't need to find someone to leave the building if the receptionist was not at the front desk. That did not help me if I was outside wanting to get in and the receptionist was not there.
6. In the parking lots of the rehabilitation center, none of the parking stops lined up with the parking spaces, making for a rather confusing jumble of parking spaces. While there might have been enough spots for two or three more cars, because of the mismatching lines and parking stops, cars would be parked haphazardly in the lots, wasting space.

I'm not sure what the purpose of such a structure could be, perhaps a place to sit down? But there were benches along the path. Perhaps stairs to Narnia?

Perhaps?

He seemed very keen on keeping this corner of the store to himself. I let him be.

I took the quiz, which asks for the definitions of 100 words (twenty each from a basic list, intermediate list, advanced, export and grandmaster) and from that, estimates how many you know. I missed 6 out of the 100 words (two from the advanced category, and four from the grandmaster) and so, according to this quiz, my vocabulary consists of some 76,000 English words, for what it's worth.
