### In Topic: Finding the current average of an indefinitely increasing sequence

28 October 2015 - 07:46 PM

Another really simple way to do it is to do

newAverage = prevAverage * (i - 1) / i + newValue / i;


, where i starts at 1 and increments after every time you want to add something to the running average. Granted, this is only as good as the floating point precision you're using, but then again, that could be said about almost everything

### In Topic: Smoothed Particle Hydrodynamics

That might be something I'm confused about. From what I understand, the Navier-Stokes equation takes the form

$$\rho(\frac{Du}{Dt}) = F_{pressure} + F_{grav} + F_{viscosity}$$ ,

which would imply that the gravity force IS dependent on the density of a particle, unless the density there is talking about the rest density. If that's the case, then I'm very confused.

And I'll look at those links, thanks!

My high score in the Chrome "webpage unavailable" dino-jump game, however, is 25,372.
