What order of magnitude is 1e4?

Asked by scruffpuff (187

I was looking at a slide deck this morning and the presenter keeps referring to doing loops in iterations of 1e4, 1e5, etc…

I tried googling this but haven’t found a clear answer. Is 1e4 100? 1000? 10,000?

10,000. Try Googling 1*(10^4)

10,000

Scientific notation is 10 “raised to the power of” the numeral you see.

So, 1E2 = 100, 1E3 = 1000, etc.

1e4 is 10,000 indeed but I get the impression the slide deck may have been talking about Big O Notation, which is a very important concept in computer science when it comes to optimizing algorithms.

@timtrueman I think the deck was actually just referring to 10,000 loops. It’s a very simple presentation on optimization in Actionscript. But that’s an interesting read on Big O. I’ve never heard of that before.
