Query for all the naysayers ... which would you rather have fast floating point operations or 15 places of accurate precision? Most of my work four places is good enough and I wrote a hurricane damage simulator.

 Four is often overkill.
You'll never get very far if all you do is follow instructions.

Why can't we have both? Not both in the same thing, but two different types, one for each.
But if I had to choose, give me the fast but counter-intuitive and weird thing. You can't emulate fast. You can emulate accuracy, if necessary.

We do have both, their are libraries that allow for infinite precision just peeps don't use them because they are slow. (Infinite subject to limits of hardware)
|
|
|
|
|
Right, so why ask us to choose?
|
|

I would like to have a bunch of smart developers, you know the ones able to write hurricane damage simulators using only four places of precision.
THESE PEOPLE REALLY BOTHER ME!! How can they know what you should do without knowing what you want done?!?!

I can to it with 8 bit integers!
It won't be a even slightly accurate simulation, of course, but...

You find yourself in a small Sailboat 10 miles East of Cuba.
There is a Class 5 Hurricane approaching from the South at 10 miles per hour.
You'll never get very far if all you do is follow instructions.

So, provided I can do 11 mph due north, I'm fine and dandy!
(I don't want to go to Cuba today - I don't smoke)

Instead of running before a speeding object, I'd recommend stepping aside.
Go West.

Depends how fast I can move, and the size and initial distance to the storm.
Going west means I need to move faster than running directly away.

Size!
..that's the thing I did not take into account. Ah, just a small bug

There's always something, isn't there?

i have a couple of image processing fns which input and output BYTEs but need to convert the input to doubles for the internals because even floats run out of precision well within reasonable parameters.
i'd love to be able to not have to use 24 bytes per pixel, but...

er, bits?
But, as we all know - palletized images suck when it comes to performing any real manipulation on them, since you're stuck with looking-up the 24 bit values anyway.
Alpha-blending images with a pallette? :shudder: Uhhhrgh! Please dont make me do that again. Recomputing a new pallete is more effort than the image processing itself.

no, BYTEs.
doubles are 8 bytes each. 3x8 = 24 bytes.

Of course. Must be about time for bed for me...
Those images sure do get pretty big, pretty quick, at that rate of memory consumption.

For pallet(e)s, all you need is scrub wood and nails. Palettes on the other hand...

Mine isn't nearly as accurate. Wind fields in real-life are surprisingly non-deterministic and literally change with the phase of the moon.

So do I! Oh no... It's a full moo OOOOOOOOOOH!!! *Howl*
It's an OO world.
public class SanderRossel : Lazy<Person>
{
public void DoWork()
{
throw new NotSupportedException();
}
}

But phases of the moon are VERY deterministic.
