Yes, floating-point arithmetic says: '0.8!=0.1+0.7'.

Will we discuss this now?

What proposal? I'm talking about elementary arithmetic.

Hi!
If you are about the proposal, then '0.1 + 0.7 !==
I think your solution by changing precision is not good enough because float
summation is still not working properly.

Hi, everyone!
Original PR and description see: https://github.com/php/php-src/pull/3460.
Because of the accuracy constraint set by the 'precision' variable, debugging
problems often occur, and many developers consider the limited accuracy to be a
feature of the language.
For better
