Compatibility: Symphony 1.7 To install, copy the folder davethegr8 to the campfire folder. The RNG will show up in your Data Sources under Controllers.

A random number generator. Returns 10 decimal values in the range 0..1. To get an integer value between 1 and 10, do the following.

        <xsl:value-of select="floor(random/number[1] * 10) + 1" />

      

Why? floor(n * 10) produces, with only one exception*, values from 0-9. To get 1-10, you add on one. So to generalize the code above, take the decimal number, multiply by the range + 1, and then add the minimum number.

        <xsl:value-of select="floor(random/number[1] * (range + 1)) + min" />

      

• When the random number is equal to the absolute max of all possible random numbers, the value will be 1.0. However, given the range of the numbers generated from mt_rand(), it is possible to assume that this will never happen. And even if it does happen, it will also be very unlikely that it will happen again.
