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***!!

Use Decimal

@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.

@C-sucks

import decimal

It is a standard python library for numbers that cannot have fucked up addition like that. Like for numbers you use for finance. It guarantees decimal precision to be spot on. Now, because it is not regular floating point it is not going to be accelerated at all.

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.
