Because even a long (64-bit int) is too small :)
A long can hold 2^64-1 = 1.84E19
A double can hold 1.79E308
Double does some black magic with an exponent, and can hold absolutely massive numbers!
Double also has some situations that it defines as “infinity”, a concept that does not exist in long as far as I know (?)
Doubles have a much higher max value than ints, so if the method were to convert all doubles to ints they would not work for double values above 2^31-1.
(It would work, but any value over 2^31-1 passed to such a function would get clamped to 2^31-1)
I actually have aphantasia :)
I get open-eyed distortions and wavyness, and can see some images with my eyes closed. I have very little control over what I see, and it is more like short glimpses, but it is tons more interesting than the black void I usually stare into with my eyes closed!
I just use my regular wrench and say “click” out loud when it feels nice and tight
Sounds very similar to ESTA, which you have to get as a european visiting the US.
This one is a lot cheaper though, 8$ for 3 years, ESTA costs 14$ a year + 7$ at the port of entry (usually included in your airline ticket). Canada has this as well, ETA, which is also a lot cheaper.
Depends, how much do you care, and how good does your car still look?
If you drive a pristine car that you plan on selling eventually: get it done at a bodyshop.
If you drive an older car or plan to keep it until it dies, and dont care about the looks too much: chrisfix has some good videos on working with a paint pen
If you drive a 20 year old car in the rust belt: lol
Because paying a few grand a year for a certificate somehow makes your software more trustworthy
