Here's something weird - when passing double absoluteLargest, any
value, to function findRootWidth, it always shows up as value
2.233392082528404e-308 at the start of the function.
If I enable #include <iostream> in the source file, the correct value
shows up in the function.
Any more thoughts?

How are you compiling your code? Are you using g++ or gcc and

Here is what I have:
medusa:/tmp/stdtest jdaniel$ diff FindColWidths1.cpp
FindColWidths2.cpp
3c3
< //#include <iostream> //........................Here is the line
in question...........................
---
> #include <iostream> //........................Here is the line in

medusa:/tmp/stdtest jdaniel$ g++ -o run1 stdtest.cpp
FindColWidths1.cpp
medusa:/tmp/stdtest jdaniel$ g++ -o run2 stdtest.cpp
FindColWidths2.cpp
medusa:/tmp/stdtest jdaniel$ ./run1 > run1.txt
medusa:/tmp/stdtest jdaniel$ ./run2 > run2.txt
medusa:/tmp/stdtest jdaniel$ diff run1.txt run2.txt
medusa:/tmp/stdtest jdaniel$
medusa:/tmp/stdtest jdaniel$ diff run1 run2
Binary files run1 and run2 differ
This really makes no sense because this #include is not in the
source file with the IO statements. It isn't needed in that file at
all. There has got to be something else.

Well, I just dled and installed XCode 2.41, and the behavior has
not gone away. Any more ideas?

Which version of GCC are you using? What does gcc_select return
on your machine? This is my output.
medusa:/tmp jdaniel$ gcc_select
Current default compiler:
gcc version 4.0.1 (Apple Computer, Inc. build 5363)

As you can guess, I'm not very experienced at this. I've had to
get a POS PC for some coursework that I'm taking, so tried to
compile the same project in Dev-C++. The above behavior is not
exhibited in that environment, so I'm mystified. If anyone's
interested, here's the code:
