Bad Programmina analogy

Firstly, VERY OLD. Secondly, Pi may change, it was once defined as 4, and also as 3. Also of interest is the Feynman Point.

Now im not one for second guessing Xerox wanting to change the fundamental laws of the universe.. but.. The primary purpose of the DATA statement is to give names to constants; instead of referring to pi as 3.141592653589793 at every appearance, the variable PI can be given that value with a DATA statement and used instead of the longer form of the constant. This also simplifies modifying the program, should the value of pi change." - FORTRAN manual for Xerox computers ?????

But how can they know? No-one has ever found an exact numerical representation of pi. How do you know it has changed, if you never knew previous the value?

((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))Exactly. It's only been calculated to a trillion digits, and if you hardcode that and then someone calculates it to a quadrillion then you're going to feel a little silly having to update the value of pi each place you hardcoded it.

sounds like a very dry joke, to me.

I always thought that 9 was a bit too much. Can you knock it down to 8.5 for me?
I wanna be a eunuchs developer! Pass me a bread knife!
No, sorry, I only work with integers. It must be either 8 or 9.

Well you never know what could happen in the universe. That's fine assumption. I usually create constants for all the decimal digits 0-9 so that I can change the value if I need it.

Yeah, but what happens when a new number is discovered between 6 an 7? :)

Ok, let me see, search for a trillion digit value in your source files and replace it with a quadrillion digit value? When that is done your great great grandson will be born. :)

I worked with some guys who previously had some offshore developers actually do that after they were told to change the hardcoded numbers to constants. (So statements like
x += 2;got changed tox += TWO;. It's fortunate they didn't use pi, else it would have become THREE_POINT_ONE_FOUR_ONE_FIVE_NINE.... )Anyone who thinks he has a better idea of what's good for people than people do is a swine. - P.J. O'Rourke
