Functions
template<class T>
T	clamp (const T &value, const T &minValue, const T &maxValue)
	Returns the given value clamped between the given minimum and maximum.
template<class T>
T	extreme (T v1, T v2, T center)
	Returns the value furthest from the center.
template<class T>
T	floor (T x)
	Returns the largest integer smaller than the argument given.
template<class T>
T	frac (T x)
	Returns the fractional part of a float or double.
template<unsigned int n, class T>
void	integrate (T samples[])
	Integrates a sequence of numbers.
template<class T>
T	lerp (const T &value, const T &inputMin, const T &inputMax, const T &outputMin, const T &outputMax)
	Linearly interpolates a value between a given range.
template<class T>
T	line (const T &value, const T &inputMin, const T &inputMax, const T &outputMin, const T &outputMax)
	Otherwise, the returned value is outputMin + ((value - inputMin) / (inputMax - inputMin)) * (outputMax - outputMin).
template<class T>
T	max (const T &v1, const T &v2)
template<class T>
T	min (const T &v1, const T &v2)
template<class T>
T	mod (const T &value, const T &minValue, const T &maxValue)
	Returns the modulus of a number in a specified range, that is (min + value mod (max - min)).
template<class T>
T	ramp (const T &value, const T &inputMin, const T &inputMax, const T &outputMin, const T &outputMax)
	If the value is below the inputMin, the outputMin is returned.
template<class T>
T	reflect (const T &value, const T &minValue, const T &maxValue)
	Returns a number reflected between the bounds.
template<class T>
T	sigmoid (const T &value, const T &inputMin, const T &inputMax, const T &outputMin, const T &outputMax)
	This function is a smooth aproximation for lerp.
template<class T>
T	step (const T &input, const T &inputThreshold, const T &outputMin, const T &outputMax)
	Returns the one of two outputs, depending on whether the input value exceeds a given threshold.
