a javascript implementation using a taylor series to approximate the square root of a number (my own original work)

sqrt

function squareRoot(value, precision)
{
    function calcSeedVal(value, precision)
    {
    	var a = 0;
    	var result = 0;
        
        if(value > 9)
        {
            a = value / Math.pow(10,precision);
            
            if(a >= 10)
            {
                result = 600;//6 * (Math.pow(10,2));
            }
            else
            {
                result = 100;//2 * (Math.pow(10,2));
            }            
        }
        else
        {
        	result = value / 10;
        }
        
        return result;
    };

    var result = calcSeedVal(value, precision);
    
    for(var i = 0; i < precision; i++)
    {
    	result = (0.5) * (result + (value / result));
    };
    
    return result;
};
