me asking python: is (0.1 + 0.2) == 0.3 ?
python: NO
me: wha.!!
python: Instead, it's 0.30000000000000004
me: what the actual F***!!

@Demolishun I don't get it, mate. What decimal.

It's a floating point issue. There are several numbers which has no representation in binary so there are libraries in many languages which are facing this problem.

https://docs.python.org/3/library/...

Use rounding tbh

round (0.1 + 0.2, 3) == 0.3

This will work just fine, no imports needed (decimal is an imported type)

"Python", and every other language with finite precision floating point accuracy numbers.

that's why you should understand hardware too, just knowing "python" doesn't make you a programmer.

Welcome to floats.

Floats allow us to weed out juniors who don't understand decimal precision or how to read a manual.

what @C0D4 said.

It works in C:

#include <stdio.h>

int main()

{

auto a=0.1;

auto b=0.2;

auto c=0.3;

printf("%s\n",a+b==c?"True":"False");

}

Of course, the reason why it prints "True" has nothing to do with floating point precision.

@theabbie damn ,burned. You just RIP him.

Luckily you didn't ask this in Stackoverflow , otherwise you will be gnagband like you are in PornHub.

@happygimp0 but unfortunately his name suggests he hate C.
