I remember reading somewhere (probably it was on Slashdot), that 
Microsoft has abandoned POSIX compliance in Windows.  I don't know how 
this might affect the Perl POSIX module.

What do you mean by "a clean build". Wasn't the Posix module included in
your basic build?

Subject: trigonometrics
The basic 5.6 Perl build is missing tangent 'tan()' and arctangent 'atn()'
functions :( and I don't want to use posix module etc as the script has to
run on a clean build - don't ask - far too complicated to explain.
So - does any budding mathematicians out there please know how to emulate
these two functions using the simple math functions that are available ?
Is there some correlation with sine and cosine etc ?

I missed that day at school - I guess.

Cheers
