[Math_Random]
[Math_Random] returns a random number. This tag can be used to return a random number between the required -Lower and -Upper parameters inclusive.
If both -Lower and -Upper are integer values then a random integer between them will be returned. The integer can be the -Lower value, -Upper value, or any value in between. If the optional -Hex parameter is specified then the random number will be output in hexadecimal notation.
If either -Lower or -Upper is a decimal value then a decimal value between them will be returned. The precision of the returned decimal value is automatically set to the maximum precision of the -Lower and -Upper parameters, but the value is not rounded.
Note: When returning integer values [Math_Random] can return at most 32-bit values (between approximately +/- 2,000,000,000).

[Math_Random: -Lower=Minimum, -Upper=Maximum, -Hex]Examples
To generate a random HTML color:
Use the [Math_Random] tag to generate three random hexadecimal numbers between 16 and 255. The following code creates a table cell with a random color.
[Variable: 'Color'=(Math_Random: -Lower=16, -Upper=255, -Hex) +
(Math_Random: -Lower =16, -Upper=255, -Hex) +
(Math_Random: -Lower =16, -Upper=255, -Hex)]
<table border="1" cellpadding="9" cellspacing="0">
<tr>
<td bgcolor="#[Variable: 'Color']">
[Variable: 'Color']
</td>
</tr>
</table>Result:
<table>
<tr>
<td color="#05D4A1">
[Variable: 'Color']
</td>
</tr>
</table>
