minus-squaresocsa@piefed.sociallinkfedilinkEnglisharrow-up1·27 days agoFreshmen engineer: wow floating point numbers are great. Senior engineer: actually the distribution of floating point errors is mindfuck. Professional engineer: the mean error for all pairwaise 64 bit floating point operations is smaller than the Planck constant.
