I know this is for fun, but as general advice to the homies, if a language or system is doing something you didn’t expect, make sure to look at the documentation
Probably not an article about integer parsing, though. If the docs are that long, then because Microsoft does have a tendency to be overly verbose for things they think you need, just to have no docs for the stuff you actually need.
…and of course JS made it into the examples, how could it not:
A programming language’s standard library usually provides a function similar to the pseudocode ParseInteger(string, radix), which creates a machine-readable integer from a string of human-readable digits. The radix conventionally defaults to 10, meaning the string is interpreted as decimal (base 10). This function usually supports other bases, like binary (base 2) and octal (base 8), but only when they are specified explicitly. In a departure from this convention, JavaScript originally defaulted to base 8 for strings beginning with “0”, causing developer confusion and software bugs. This was discouraged in ECMAScript 3 and dropped in ECMAScript 5.
But I’m too busy being confused by the behaviors of libraries I previously didn’t read the documentation for, to read the documentation for every new library I adopt.
oh god the reason is even stupider then I expected
Because large numbers use the e character in their string representation (e.g., 6.022e23 for 6.022 × 1023), using parseInt to truncate numbers will produce unexpected results when used on very large or very small numbers. parseInt should not be used as a substitute for Math.trunc().

This will save a lot of time and headaches
Holy fuck that is long. When the documentation for the integer parsing function is 10 pages long, there’s something seriously wrong with the language
Is it? I’ve seen longer articles for C# and not as many complaints about it.

For reference here’s the relevant rust docs.

I’d advise to always look into the corresponding documentation before using something from any library.
I’ll go with 5 hours of debugging, thank you very much!

(This is sarcasm…mostly.)

Okay but this documentation is obviously wrong from the first sentence
Integers don’t have radices. It should read:
Either way, I still don’t understand the behaviour in the image.nvm, thanks [email protected]
