Obliterating the performance of a calculator wasn't enough, they actually managed to introduce some all new usability regressions as well. They decided to localize inputs so now periods don't work depending on your locale. Copying numbers also includes the formatted and localized output as well instead of the raw value. Parsers are going to love those commas.

We're reaching Microslop levels we never thought possible. I actually think Claude Code would have done a better job.

Be grateful we are talking about a desktop OS where you are free to not use the built-in apps and even install an arbitrary calculator of your choosing. Unlike dozens of built-in "Apps" on mobile platforms that just exist and you can either use them all as provided, or switch to (Apple or Android).
