Pragma Lines

[Greenswordfish1]

I'm having a difficult time differentiating the meaning of the ^ code

For example
pragma solidity ^0.8.0;

Does that mean all versions UP TO 0.8.0 and including 0.8.0 or 0.8.0 and ABOVE?

Many of the definitions are confusing. I've heard 2 people explain them and say the opposite for this. Thank you

^ creates a range of versions you can use to compile the contract. The range starts at the version that you specify.

In this case you can compile your contract in any version from 0.8.0 to the last, it includes 0.8.0 but you can try it out in Remix.

@Greenswordfish1 ^0.8.0 == greater than or equal to 0.8.0 simple.

[Greenswordfish1]

Would these two mean the same thing? pragma solidity ^0.8.0 & pragma solidity >= 0.8.0 < 0.9.0

[pacelliv]

Yes, they mean the same thing and that's precisely what the caret does, so in that case the second syntax is unnecessary in my opinion.

^0.8.0 means greater or equal to 0.8.0.
>= 0.8.0 < 0.9.0 means greater or equal to 0.8.0 and less than 0.9.0.

0.9.1 version will work with the first one but it will not work with the second.
