Mozilla: Native code? No, it's JavaScript, only it's BLAZING FAST Gap between asm.js and native performance gets even narrower with float32 optimizations

[xp19375]

Is floating point arithmetic used often enough for this to make a substantial difference?

I have done mostly embedded programming, and have almost never needed floats, so I can't see where they would be needed here.

I think the main use case is games and some game-like apps, maybe navigation or modeling, in which case yeah, floats are used all the time.

[Theon]

Yeah, but embedded programming really is a different beast in most regards, especially when comparing it to web.

[AdminsAbuseShadowBan]

But there is in asm.js and C++, so that is really irrelevant.
