regularizedGamma -- upper regularized gamma function

Synopsis

Description

This is the (upper) regularized gamma function \(Q(s, x) = \frac{\Gamma(s,x)}{\Gamma(s)}\).

i1 : regularizedGamma(3, 7)

o1 = .0296361638805218

o1 : RR (of precision 53)
i2 : Gamma(3, 7) / Gamma 3

o2 = .0296361638805218

o2 : RR (of precision 53)

Caveat

This function always returns a double precision real number (53 bits) regardless of the precision of its arguments.
