Why do floating-point numbers even exist

Why is it so hard for CPU-making Jews to implement fast arbitrary-precision arithmetic or at least fixed-point numbers?

You live in a medium-sized city. Would you rather drive a relatively slow car that will safely take you to your destination, or would you drive a supercar with absolutely no safety devices just because you gotta go fast?

If BCD is implemented in hardware and everything else is built around it, why do you care about speed? Jewtel could, you know, replace some of the movxasdf_ebin instructions with moderately fast BCD instructions.
