title: Name for [-1.0, 1.0] range
body: <p>I am in the process of putting together a small library that requires the use of <a href="https://en.wikipedia.org/wiki/Saturation_arithmetic" rel="nofollow noreferrer">saturation arithmetic</a>.</p>
  
  <p>As a part a part of this I am intending to implement two specialised cases of floating point types that are clamped to the [0.0, 1.0] and [-1.0, 1.0].</p>
  
  <p>In terms of naming the [0.0, 1.0] range I found the following two questions that seemed quite helpful:</p>
  
  <ul>
  <li><a href="https://stackoverflow.com/questions/34515311/how-to-name-value-with-range-of-0-0-to-1-0">Question
  1</a></li>
  <li><a href="https://stackoverflow.com/questions/672860/clear-standard-name-for-a-unit-range-0-1">Question
  2</a></li>
  </ul>
  
  <p>But I am struggling to find a a way of naming/expressing the [-1.0, 1.0] range. I think part of this is related to the way search engines treat the negation sign on numbers, but it could just be that it has no special name.</p>
  
  <p><strong>Is there a special name for this range or a reasonably short way of describing it that would be suitable for use in a type name?</strong></p>
  
  <p>I did also consider asking this on mathematics, but as I am primarily a programmer and have a slight aversion to maths, I felt more confident asking here first in case I got bombarded with terminology and equations I didn't understand.</p>
  
  <p>I find it odd that certain sequences/categories of numbers have special names (e.g. fibonacci sequence, mersenne primes) but such important ranges seemingly do not.</p>
