UTPF	Upper-Tail Snedecor’s F Probability given numerator
	degrees of freedom and denominator degrees of freedom
	(of the F distribution), evaluated at value. Returns the
	probability that a Snedecor's F random variable is
	greater than value.
	UTPF(numerator, denominator, value)
UTPN	Upper-Tail Normal Probability given mean and variance,
	evaluated at value. Returns the probability that a normal
	random variable is greater than value for a normal
	distribution. Note: The variance is the square of the
	standard deviation.
	UTPN(mean, variance, value)
UTPT	Upper-Tail Student’s t-Probability given degrees of
	freedom, evaluated at value. Returns the probability that
	the Student's t- random variable is greater than value.
	UTPT(degrees, value)

Real-number functions

	Some real-number functions can also take complex
	arguments.
CEILING	Smallest integer greater than or equal to value.
	CEILING(value)
	Examples
	CEILING(3.2) returns 4
	CEILING(-3.2) returns -3
DEG→RAD	Degrees to radians. Converts value from Degrees angle
	format to Radians angle format.
	DEG→RAD(value)
	Example
	DEG→RAD(180) returns 3.14159265359, the
	value of π.
FLOOR	Greatest integer less than or equal to value.
	FLOOR(value)
	Example
	FLOOR(-3.2) returns -4
