Function: string Meter2Feet(float meter);

Returns a string of metric value meter converted to feet/inch in common representation, ie. 3' 4 5/16".

• float meter distance in meters, any valid float, positive or negative

Specification

string Meter2Feet( float meter )
{
	float fraction = meter / 0.3048;	// Compute feet
	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)	// show fraction value only if not zero
		strFraction = " " + (string)llAbs((integer)fraction) + "/16";
	
	return ((string)feet + "' " + (string)llAbs(inches) + strFraction+ "\"");
}

Example

Trivial example to listen to any chat from the object owner for meter values and respond feet/inch value.

string Meter2Feet( float meter )
{
	float fraction = meter / 0.3048;	// Compute feet
	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)	// show fraction value only if not zero
		strFraction = " " + (string)llAbs((integer)fraction) + "/16";
	
	return ((string)feet + "' " + (string)llAbs(inches) + strFraction+ "\"");
}

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));
	}
	
	touch_start(integer n)
	{
		llOwnerSay( Meter2Feet( llVecDist( llGetPos(), llDetectedPos(0))));
