====== Random() ======
Category:  Number function

\\ 
=====Description=====
This function generates a random number between 0 and 1.

\\ 
=====Arguments=====
This function does not require arguments.

**Return value type:**  Number

\\ 
=====Remarks=====
====Generating random numbers within a given range====
To generate a random number between a specific minimum and maximum value, use the following calculation  (extra spaces have been added for clarity):

  ( random() * ( [number of values in range] - 1) ) + [minimum value]

The expression to generate a random number between 1 and 10 would be the following:

  ( random() * (10-1) ) +1 
or
  ( random() * 9 ) +1

The expression above will provide a decimal result you will need to round for an integer result:

  roundxl( ( random() * 9 ) +1 , 0 )  //Excel-style rounding
\\ 
====Determining the number of values in a given range====
The number of values in a given range is determined as:
  (max value) - (min value) + 1
This can be deceiving at first glance.  For example, the range between 20 and 40 includes //21// values.


\\ 
=====Examples=====
Extra spaces added for clarity.
  random() //Returns 0.37130572949209748204

  ( random() * 10 ) +2   //Random number between 2 and 12, unrounded.

  roundxl( ( random() * 20 ) +20 , 0 )  //Random number between 20 and 40, rounded to an integer.
