Functions
static double	ceilDecimal (double x, int decPow)
	rounds x up to the next decimal power 10 ^ decPow
static double	roundDecimal (double x, int decPow)
	rounds x to the next decimal power 10 ^ decPow
static double	intervalTransformation (double x, double left1, double right1, double left2, double right2)
	transforms point x of interval [left1,right1] into interval [left2,right2]
double	linear2log (double x)
	Transforms a number from linear to log10 scale. Avoids negative logarithms by adding 1.
double	log2linear (double x)
	Transforms a number from log10 to to linear scale. Subtracts the 1 added by linear2log(double).
bool	isOdd (UInt x)
	Returns true if the given interger is odd.
template<typename T >
T	round (T x)
	Rounds the value.
static bool	approximatelyEqual (DoubleReal a, DoubleReal b, DoubleReal tol)
	Returns if a is approximately equal b , allowing a tolerance of tol.
template<typename T >
T	gcd (T a, T b)
	Returns the greatest common divisor (gcd) of two numbers by applying the Euclidean algorithm.
template<typename T >
T	gcd (T a, T b, T &u1, T &u2)
	Returns the greatest common divisor by applying the extended Euclidean algorithm (Knuth TAoCP vol. 2, p342). Calculates u1, u2 and u3 (which is returned) so that a * u1 + b * u2 = u3 = gcd(a, b, u1, u2).
