calculators not working correctly when inputing large numbers on multiple browsers !

[Mathieu M.]

my calculator is not working correctly when inputing numbers larger than 4 digits... Not going to be easy to analyse deals....it returns a NaN when I want to input more than 4 digits... I'm on a mac air M2 Chrome and it also does not work on safari, brave, Opera, and tor !

(And YES! i reset the cache, reinstalled the browsers )

suggestions ? 

thanks
