OK, so we've seen these kind of "numbers" before
-
decimal Zero = 0.0M;
decimal One = 0.0M;
decimal Var = 0.0M;
[snip]
if( Zero == decimal.MinValue || One == decimal.MinValue )
Var = decimal.MinValue;
else Var = Zero - One;
I'm barely finding this stuff funny anymore.
-
This is the first thing I've seen in a while that actually made me pause and puzzle for a minute to figure out what the Hell the coder was thinking.
If "zero" (0.0M) or "one" (0.0M) is the minimum value for decimals, set var to the minimum value for decimals, otherwise set it to zero minus zero (aka, "one").
WTF.

May God have mercy on the person who wrote this.
This makes implementing a recursive greater-than operator look sane.
function gt(n, m) { return n == 0 ? false : m == 0 ? true : gt(n - 1, m - 1); }

I like what happens when you use negative numbers.

The values for Zero and One actually do get changed somewhere in the [snip] section. Finally figured out what they were for.
One stores a piece of data from 1 year ago; Zero for the current year's data (0 years ago). Even so, improved naming scheme, please.

I think this looks better in Scheme:
(define gt (lambda (x y) (if (or (eq? x 0) (eq? y 0)) (and (not (eq? x 0)) (eq? y 0)) (gt (- x 1) (- y 1)) )))
usage: (gt x y)
Notes:
-Behavior fixed to be greater than instead of greater than or equal to.
-Desired business logic for negative numbers preserved.
:D

Where do you think I got it from?

And now knowing where I got it from, you can assume I did NOT, in fact, make that mistake. Try it.

Are you saying that you meant to keep the infinite loop when both numbers are negative integers?
-
gt( 2, 2 ) == True
That's greater than or equal ..

Absolutely. What's your point, exactly? My code works like so:
gt(2, 1) => true
gt(2, 2) => false
gt(1, 2) => false

Or floating-point numbers.

Read that wrong on first glance.

Of course. It's a feature, not a bug. You can't argue with business logic.
