What's the best free and open source calculator? I'm tired of opening up python to calculate my life savings.

Also why does it show 287.5399...6 instead of 287.54?

casio are cheap and good (7400gii and 9750gii are recommended)
hp 48, 49 and 50 are really good
ti is garbage, avoid at all costs

can you tell me what based means now? :D

This. bc is everywhere.

What math are you trying to do? I can do basic arithmetic by typing it into duckduckgo. Complex math I use a physical calculator or wolfram|alpha.

Casio is shit and if you've ever used a TI you'd know that it is the best. I got a used TI-89 titanium years ago for next to nothing and it kicks ass. It can even run games written in BASIC.

because some numbers are periodic in binary thus your computer can't fully store them and has to truncate them somewhere

try 0.1 + 0.2 in python or java or whatever

kys faggot

as to your question
just use the calculator that comes with the OS, and use an OS that isn't retarded like Windows or Linux Mint, you can also just type in simple arithmetic into Google, or Google an online calculator
