Specification

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);
}
