'''All''' of these commands work with ''and/or'' return a generic type [[Number]].
 
In the scripting language (unlike config's) there is no specialty types such as float or integer. All numeric values are represented solely as a [[Number]] type.
 
'''However''', specific commands listed below ''expect'' specific types of value ''e.g.'' [[Number#Radians|Radians]], [[Number#Degrees|Degrees]], and floats.
 
Be aware that although not directly related to the list below '''many''' commands in the scripting language restrict the range of possible values. Particularly commands wanting ratios between <tt>0.0</tt> and <tt>1.0</tt> (''e.g.'' no <tt>''integer'' &gt; 1</tt> is possible). Check individual documentation for the command itself.
 
Also, the [[Boolean]] is a true type in command syntax. The results (the return value) of the below list should not be used directly in a boolean type expression(s).
 
;Bad:<code>a = [[abs]] -3;<br>? (a) : [[exit]];</code>
 
;Good:<code>? (a > 0) : [[exit]];</code>

==Commands Introduced with Arma 3 v1.22==
In {{GVI|arma3|1.22}} the following math commands were added to simplify vector management. See [http://forums.bistudio.com/showthread.php?160330-Scripting-Discussion-(dev-branch)&p=2700462&viewfull=1#post2700462 this post] for more information.
