Gotta love that Herbie also provides just `1` as alternative. "66.8% accurate, 305.0× speedup" But the expression you get if you disable "numerics" ruleset (which includes expm1) is pretty wild also: (if (<= (exp x) 4504410275303423/4503599627370496) (+ 1 (+ (* 1/24 (pow x 3)) (* x (+ 1/2 (* x 1/6))))) (/ (+ (exp x) -1) (log (exp x)))))
