	GammaIncomplete	Evaluates the incomplete gamma function.
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Log10	Returns the common (base 10) logarithm of a double.
	Log1p	Returns log(1+x), the logarithm of (x plus 1).
	LogBeta	Returns the logarithm of the Beta function.
