Re: [R] number point under-flow

[Roger D. Peng]

Did you compile with gcc-2.96?  I think there were some 
problems with the floating point arithmetic with that 
compiler (at least for the earlier versions released by Red 
Hat).

Hello,

I've come across the following situation in R-1.8.1 (compile + running under
RedHat 7.1):

phyper(24, 514, 5961-514, 53, lower.tail=T)
[1] 1

phyper(24, 514, 5961-514, 53, lower.tail=F)
[1] -1.037310e-11

I'd expect the later to be 0 or some very small positive number. Is this a
number under-flow of the calculation? Do you think I'm safe if I just set the
result to 0 in these cases?
	kind regards,

	Arne
