However, just having a picture stuck in between paragraphs does not look professional. To start with, we want centering pdf figures in latex way of adding captions, and to be able to cross-reference. Floats are containers for things in a document that cannot be broken over a page.
Floats are there to deal with the problem of the object that won’t fit on the present page, and to help when you really don’t want the object here just now. They always have a caption describing them and they are always numbered so they can be referred to from elsewhere in the text. If there is not enough room on the current page, the float is moved to the top of the next page. This can be changed by moving the Table or Figure definition to an earlier or later point in the text, or by adjusting some of the parameters which control automatic floating. Authors sometimes have many floats occurring in rapid succession, which raises the problem of how they are supposed to fit on the page and still leave room for text. The skill is to space them out within your text so that they intrude neither on the thread of your argument or discussion, nor on the visual balance of the typeset pages. As with various other entities, there exist limitations on the number of floats.
However, there may be times when you disagree, and a typical example is with its positioning of figures. Once this possibility is exhausted, it will next try to place the remaining floats into top and bottom areas. After that, it starts processing document material for this page. In the process, it may encounter further floats.
It’s possible to get a thin border around all figures. The border will not include the caption. Let’s give a quick reminder here. You may feel that it is a bit long winded, but such distinctions are necessary, because you may not want all tables to be treated as a float. You have the full and absolute control about the placement of your figures and captions. It is always good practice to add a caption to any figure or table. The location of the caption is traditionally underneath the float.
