Comment on Kid gave a reasonable answer without all the math bullshit
axEl7fB5@lemmy.cafe 1 day agoAs soon as you use decimals in computer and human calculations, they become lossy.
What does lossy mean? I’m not trying to die on any hill, but I’m quite confused aswell.

By lossy I mean rounding errors. Try to combine 2 or more recurring decimals in any function and you start loosing accuracy.
Mathematicians rarely use decimals (also they rarely use numbers). Everything stays in fractions. Maybe the very last step is delivered as a decimal, but rarely.
