Are you using python?

[@plasma8321]

No. This is written in java. But the idea is the same

can u try this rounding method with 0.3 + 0.1 ? it does not work with me but it does work with 0.1 + 0.2
i don't think this rounding technique solve the problem 🙃

sorry maybe i did not get the video are u rounding the stored value or just the output ?

[@plasma8321]

@@justcurious1940 the output is rounded

[@justcurious1940]

@@plasma8321 well i used c++ and i have used a rounding function called std::round() I'm sure it works like the one u used in the video and guess what
0.4 will always gives 0.40000000000000002

@@justcurious1940 This is weird. C++ seems to round both functions automatically without even needing to do anything. Im not sure how your getting this

@@plasma8321 std::cout.precision(17) ;
std::cout

u sound so bored and not interested at all is java the reason ?

[@plasma8321]

No! I was reading a script

​@@plasma8321 its funny i'm using c++ and when i do something like this :
double x = 0.3 ;
std::cout
