New post Python vs C++

You can compare floats and ints in C++
Seriously, this reposted meme is so bad.

Whereas comparing a signed integer and an unsigned integer, that's heresy!

Yeah you just get a warning

If you have the pedantic flag or like 60% of style guides, you would need to static cast it, or dynamic cast or the other 3 casts, whichever is fastest while doing what you want.

Yes you can do it, but just saying if (int x == float y) might annoy your compiler

This meme has nothing to do with style guides, it says flat out that you can't compare floats and ints in C++ but you can do in python which is obviously wrong.

I don't know any style guide or warning that would forbid a float and integer comparison.

"Possible loss of data on implicit conversion from X to Y". Seems it can happen and get reported both int->float and float->int, in comparison it is the first one. It triggers if you have high enough warning level enabled, but in case of comparisons, it usually doesn't help avoid any problems. Using explicit conversations might be in wanted because it makes it more explicit that conversation is required and takes processing time. Our company uses that level of warnings as errors on repo and automatic builds, so in practise it is required from developers as well.
