Hey all, I currently use FreeBSD and linux and have decided I want to use a proper Unix distrobution. Which Unix distro would you members recommend. The only requirments that I have is that I can use some pogramming utilities available. I don't mind the install process. One more thing, I know some... (2 Replies)
Hello Everyone,
I'm new to this forum and Unix. I have a couple of questions and please, excuse my ignorance.
I have a spare machine which is now running MS Windows 98 and I would like to format the disk and install the Unix operating system along with Oracle 8i and SQL Server.

Is there any difference between UNIX operating system and UNIX open server? Please explain. (1 Reply)
hi
I am trying to install solaris 8 on intel machine(intel300 mhz,32 mg ram,3.2 hd,24x cd-rom). hardware scaning is ok. Then it ask to enter choice for interactive installation #1 for web #2. After i enter chice system reboot agian and it takes to same screne.

I need the Unix operating system on disc as im new to unix. Im studying unix and x windows next year at Sheffield University and would like to get a head start.
Any suggestions would be appreciated (2 Replies)
math::combinatorics(n) Tcl Math Library math::combinatorics(n)
__________________________________________________________________________________________________________________________________________________NAME
math::combinatorics - Combinatorial functions in the Tcl Math Library
SYNOPSIS
package require Tcl 8.2
package require math ?1.2.3?
::math::ln_Gamma z
::math::factorial x
::math::choose n k
::math::Beta z w
_________________________________________________________________DESCRIPTION
The math package contains implementations of several functions useful in combinatorial problems.
COMMANDS
::math::ln_Gamma z
Returns the natural logarithm of the Gamma function for the argument z.
The Gamma function is defined as the improper integral from zero to positive infinity of
t**(x-1)*exp(-t) dt
The approximation used in the Tcl Math Library is from Lanczos, ISIAM J. Numerical Analysis, series B, volume 1, p. 86. For "x >
1", the absolute error of the result is claimed to be smaller than 5.5*10**-10 -- that is, the resulting value of Gamma when
exp( ln_Gamma( x) )
is computed is expected to be precise to better than nine significant figures.
::math::factorial x
Returns the factorial of the argument x.
For integer x, 0 <= x <= 12, an exact integer result is returned.
For integer x, 13 <= x <= 21, an exact floating-point result is returned on machines with IEEE floating point.
For integer x, 22 <= x <= 170, the result is exact to 1 ULP.
For real x, x >= 0, the result is approximated by computing Gamma(x+1) using the ::math::ln_Gamma function, and the result is
expected to be precise to better than nine significant figures.
It is an error to present x <= -1 or x > 170, or a value of x that is not numeric.
::math::choose n k
Returns the binomial coefficient C(n, k)
C(n,k) = n! / k! (n-k)!
If both parameters are integers and the result fits in 32 bits, the result is rounded to an integer.
Integer results are exact up to at least n = 34. Floating point results are precise to better than nine significant figures.
::math::Beta z w
Returns the Beta function of the parameters z and w.
Beta(z,w) = Beta(w,z) = Gamma(z) * Gamma(w) / Gamma(z+w)
Results are returned as a floating point number precise to better than nine significant digits provided that w and z are both at
least 1.
