A new command and a new ``float specifier'' will allow you more control over LaTeX's float placement algorithm.
This command stops any further floating environments from being placed
on the current page.
The optional argument placement can be either
b (not both), and in this case the restriction applies only to putting
further floats at the top or at the bottom.
float placement specifier: !
This can be used, along with at least one of h, t, b and p, in the float placement optional argument.
If a ! is present then, just for this particular float, whenever it is processed by the float mechanism the following are ignored:
Note that its presence has no effect on the production of float pages.
A ! placement specifier overrides the effect of any \suppressfloats command for this particular float.
