Precisely. I also do scientific programming, where such needs are pretty
common. But the vast bulk of the world's programming involves numbers
that can be represented with adequate accuracy using single precision
floating point. For instance, how many million-dollar quantities are
actually measured with a precision of +/-$1? And how many people would
actually care if such quantities were in error by $1 or two?
