12.8.2.3 Force figure placement in text

https://tex.stackexchange.com/landing/r/digest?cta=question&id=8625

I have a problem when a lot of figures are in question. Some figures tend to "fly around", that is, be a paragraph below, although I placed them before that paragraph. I use code:

12.8.2.5 \mid,   (vertical bar), \vert, \lvert, \rvert, \divides

https://tex.stackexchange.com/landing/r/digest?cta=question&id=498

What's the difference between the different vertical bars? 
$S = \{\, x \mid x \not= 17 \,\}$ 
$a \vert b$ implies $a \leq b$ when $b \ne 0$ 
$a|b$ implies $a \leq b$ when $b \ne 0$ 
$\lvert x \rvert$ is ...

https://tex.stackexchange.com/landing/r/digest?cta=question&id=819

I would like to typeset a draft of my document with double linespacing so that my collaborators have space to write in their edits (with a pen).  How do I do it?
