That's well out of date; the Ryu algorithm, published in about 2018,
beats the pants off every other exact float output algorithm both in
speed and simplicity.

(It's hard to overstate how good it is. It's many times faster than any
previous algorithm, requires no special cases other than zero/inf/NaN,
and doesn't use any float arithmetic at all.)
