Specification

<lsl> string Meter2Feet( float meter ) {

   string sign = "";
   if (meter < 0)
   {    // Use only positive value to simplify the maths
       sign = "-";
       meter = -meter;
   }
   
   // Compute feet multiplying by reciprocal value of 
   //  conversion constant 0.3048 for performance reasons
   float fraction = meter * 3.2808398950131233595800524934383;
   integer feet = (integer)fraction;
   
   fraction = (fraction - feet) * 12;    // Compute inches
   integer inches = (integer)fraction;
   
   fraction = llRound((fraction - inches) * 16);    // Compute 1/16 inches
       
   string strFraction = "\"";
   if (fraction != 0)    // show fraction value only if not zero
       strFraction = " " + (string)((integer)fraction) + "/16" + strFraction;

   return (sign + (string)feet + "' " + (string)inches + strFraction);

Example

Trivial example to listen to any chat from the object owner for meter values and respond feet/inch value. <lsl> // Insert code of Meter2Feet user function here

default {

   state_entry()
   {
       llOwnerSay("Enter: [m]");
       llListen(0, "", llGetOwner(), "");
   }
   
   listen(integer _chan, string _str, key _id, string _msg)
   {
       float meter = (float)_msg;
       llOwnerSay(Meter2Feet(meter));
   }

}</lsl>
