# What are the default placement options for a floating figure in Latex?

The document Using Imported Graphics in L A TEX and pdfL A TEX talks about the different ways to affect where a floating figure is placed [htbp]. But these arguments are optional ...

So how is the float placed if I don't enter any options? Is not entering any options equal to [htbp] or some other combination of placement demands? If so which?

@LaRiFaRi The one thing about floats that Frank's opus does not answer is the question asked here. –  David Carlisle Apr 22 at 9:18
Just a small addition. They are optional but also restrictive. Eg if you only put [bp] then you override the default and latex is only allowed to put it in bottom or new page. Took me ages to understand the difference that it's not a preference but requirement :) –  Trefex Apr 22 at 9:23
@Trefex yes which is why using [h] is such a bad idea, as it means not top, not bottom and not on a float page, which doesn't give latex many options.... –  David Carlisle Apr 22 at 9:29
@DavidCarlisle exactly, I always use [!htb] which fits my needs for most of the cases. –  Trefex Apr 22 at 13:00
@Trefex that's almost as bad:-) It's logically dubious to have a default that you don't want and then over-ride the default on every instance of a float. Better to set the defaults that you want. –  David Carlisle Apr 22 at 13:30

article.cls defines
\def\fps@figure{tbp}

so for figures and tables the default is [tbp]
