That used to be true, but actually on processors like the ARM Cortex-M used in the Teensy 4.1 it has a remarkable little FPU. It does 32-bit FP in the same number of cycles it does a 32-bit int (although there are additional optimizations for ints)
That's why I wrote my code for maintainability. In retrospect, it was a mistake. I made an incorrect assumption about the average capabilities of FPUs on these little 32-bit systems.
To err is human. Fortune favors the monsters.

The other day I utilized WinZip and found on Edge::News::My Feed an ad and a large one at that the next day for just that product. Even more amazing to me I just now enjoyed much of a tasty bag of Cheetos my favorite item in the food pyramid except of course stale potato chips and upon viewing Edge::News::My Feed I see an ad for Chester's Popcorn. Haven't found the cameras yet.

there is no camera you are not being watched you are being controlled

Just because you are paranoid doesn't mean that someone is not out to get you.

Yes, you are being watched. They do most of their surveillance through your cell phone.
I was talking to my friend a few weeks ago about DeWalt powertools and powertools in general, and for the next 2 days all I saw were DeWalt and powertool adverts on a few of my cell phone news feed aps. Coincident, maybe, but nothing surprises me anymore.
I just put on my tin foil hat and go about my business.
Cheers.

I would say coincidence and a good example of selection bias.
I was also recently flooded with DeWalt adverts but didn't really give it a second thought. I hadn't discussed power tools with anyone or searched for them, etc.
For you it stood out as you had been talking about them when they popped up, for me it was just another ad campaign. I would imagine there are 100 other adverts that you saw in the same time period that you ignored as just "par for the course" and not related to any discussions you'd had.

That all sounds reasonable, if it only happened occasionally. But whenever I talk to my wife about any "advertisable" product, we both get hit with ads for that product within the next hour or so. We've even tested it and said the name of some project we've never searched or even considered, and boom, there's the ad.

My wife and I were walking though a department store, specifically the sporting goods section, when she said "Wow, what a coincidence, I just received a notification about a sale on treadmills at this store!". Coincidence?...not.

That's probably why I didn't receive any notifications. We differ in our opinions about this. I get a phone and turn off all data and permissions that I can, she turns on all the data and permissions that she can.

I don't get advertisements at all. My Wi-Fi is always on, but not necessarily connected. My microphone and camera are turned off, except when I allow their access. GPS is always off.

We are all being watched bro, the 21st century is in the yard ... sometimes it even seems to me that my smartphone is listening to me - after talking with a friend about a new gadget, I see an advertisement specifically on this topic

No, of course not... but can you remove the coffee can from your desk? 
|
|
|

Apparently I or someone else did as I can find no coffee can upon it despite having searched thoroughly

Haven't you received a notification that it's time to put your socks away in your room?

Thanks for informing me Just where exactly did you place the camera

You probably are, but you can as well set-up an ad-blocker and stop caring about it because you won't see any ads at all

I hardly use my cell-phone and rarely use any form of social media thereby making me somewhat off the grid.
I did have my account suspended from Facebook probably because I used it to sign into some sites with my FB credentials and they were tracking my comments.
Doesn't bother me in the least considering that the intelligence services are sweeping up so much junk data that they cannot data mine it. As a result, it has reached the point that all of the surveillance in the world has reached a point of diminishing returns.
When was the last time anyone heard it being reported that data mining such data was the foundation for stopping any type of crime?

To stop it? in "Person of Interest", in the real life... never.
To catch a criminal (after the crime was executed)... a couple of times. They were so morons to continue uploading pictures and status and whatever more to social media and some of them were easily identificable.

If something has a solution... Why do we have to worry about?. If it has no solution... For what reason do we have to worry about?

There are some wild things in the world of targetting ads and inferred information from data mining.
People have discovered household pregnancies via the plethora of junk mail arriving.
A credit card company claims with a name, timestamp, and location they can tell you who bought what even if the purchase was in cash.
