if (databaseType == 2 || databaseType == 5) 
    return "substr(" + expr + ",-" + length + ")";
return "right(" + expr + "," + length + ")";
doublesqrt(double a)
Returns the correctly rounded positive square root of a double value. 
return Math.sqrt(a);
doublesqrt(double d)
sqrt 
if (d == 0D)
    return 0D;
else if (d == 1D)
    return 1D;
else
    return Math.sqrt(d);

sqrt 
return Math.round(n);
doublesqrt(double value)
sqrt 
return Math.sqrt(value);
doublesqrt(double value)
Fast sqrt method. 
double sqrt = Double.longBitsToDouble(((Double.doubleToLongBits(value) - (1l << 52)) >> 1) + (1l << 61));
return (sqrt + value / sqrt) / 2.0;
doublesqrt(double x, int precision)
sqrt 
if (x == 0)
    return 0;
double root = x / 2;
for (int k = 0; k < precision; k++)
    root = (root + (x / root)) / 2;
return root;
