== Random negative chat channel ==
This LSL function should, according to my calculations, return a random negative integer in the range -2,000,000,000 to -1,000,000, suitable for use as a dialog chat channel.
<lsl>
integer GetDialogChannel ()
{
    return (integer) llFrand (-1999000001.0) - 1000000;
}
</lsl>
== Ordinal suffix ==
This LSL function takes an integer and returns a string that is the integer with its ordinal suffix ("st", "nd", "rd" or "th") appended.
<lsl>
string OrdinalSuffix (integer number)
{
    string result = "th"; //for all except 1s, 2s and 3s, but including 11, 12 and 13
    number = number % 100; //just the 10s
    if (number < 4 || number > 20) //exclude the teens (and their neighbours)
    {
        number = number % 10; //just the units
        if (number == 1) result = "st"; //*1st
        else if (number == 2) result = "nd"; //*2nd
        else if (number == 3) result = "rd"; //*3rd
    }
    return (string) number + result;
}
</lsl>


== Format a metric measure to Imperial (or US) units, with fractional inches ==
This LSL function takes a float value representing a measure in metres and returns a string representing the equivalent Imperial (or US) measure in feet and inches, rounded to the nearest quarter inch, and expressed using the feet and inches symbols ' and ", and the fractional characters ¼, ½ and ¾.
<lsl>
string FormatImperial (float metres)
{
    string result = "";
    float inches = metres / 0.0254;
    integer whole_inches = (integer) (inches + 0.125);
    float part_inches = inches - (float) whole_inches;
    integer whole_feet = whole_inches / 12;
    whole_inches = whole_inches % 12;
    if (whole_feet) result += (string) whole_feet + "' ";
    if (whole_inches) result += (string) whole_inches;
    else if (part_inches < 0.125) result += "0";
    if (part_inches >= 0.625) result += "¾";
    else if (part_inches >= 0.375) result += "½";
    else if (part_inches >= 0.125) result += "¼";
    return result + "\"";
}
</lsl>
