I've come to realize that 50% of numerical analysis mistakes that I make are due to overusing the approximation 1/(1-x) ~ 1-x It always works for concentration inequalities, but burns you in fixed pt (its _okay-ish_ in float)

Me personally, I use the approximation log(n!) = n log n - n. Somehow I always get things wrong with this…

You’re only missing a 1/sqrt(2*pi*n) though
