Specification

string Meter2Feet( float meter )
string Meter2Feet (float meter)
{
	integer negative = FALSE;
	if (meter < 0)
	{	// Use only positive value to simplify the maths
		negative = TRUE;
		meter *= -1;
	}
	
	float fraction = meter / 0.3048;	// Compute feet
	integer feet = llFloor(fraction);
	
	fraction = (fraction - feet) * 12;	// Compute inches
	integer inches = llFloor(fraction);
	
	fraction = llRound((fraction - inches) * 16);	// Compute 1/16 inches
	string strFeet = (string)feet;
	
	if (negative)	// Reallocate sign to ensure showing up in case feet value is zero
		strFeet = "-" + strFeet;
	
	string strFraction = "\"";
	if (fraction != 0)	// show fraction value only if not zero
		strFraction = " " + (string)(integer)fraction + "/16" + strFraction;

	return (strFeet + "' " + (string)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)
{
	integer negative = FALSE;
	if (meter < 0)
	{	// Use only positive value to simplify the maths
		negative = TRUE;
		meter *= -1;
	}
	
	float fraction = meter / 0.3048;	// Compute feet
	integer feet = llFloor(fraction);
	
	fraction = (fraction - feet) * 12;	// Compute inches
	integer inches = llFloor(fraction);
	
	fraction = llRound((fraction - inches) * 16);	// Compute 1/16 inches
	string strFeet = (string)feet;
	
	if (negative)	// Reallocate sign to ensure showing up in case feet value is zero
		strFeet = "-" + strFeet;
	
	string strFraction = "\"";
	if (fraction != 0)	// show fraction value only if not zero
		strFraction = " " + (string)(integer)fraction + "/16" + strFraction;

	return (strFeet + "' " + (string)inches + strFraction);
}
