0 vs. 00

String values are handled differently... each "letter" has it's own 8-bit value. Assuming we're using ASCII notation, the 8-bit value for 0 is 00110000, which would be repeated twice for 00, so 0011000000110000. 11 would be 0011000100110001.

Of course, there are many different types of character encoding schemes (UTF-8, UTF-16, UTF-32, ISO8859, Windows 1252, and many many more, all of them work similarly to ASCII, but the actual binary value of a particular character may be different)



You may commence shouting "Shut Up, Nerd!" at me at your earliest convenience.

No, that was helpful. Very helpful!!!!

FWIW, here's what our charter clinician said:

"As you know, according to rule 3-4-3d. A team shall not have both #'s of 0 and 00.

Simply a clerical thing here. The intent isn't to penalize a team in this situation."

Perfect, perfect, perfect! I almost spewed Mt. Dew on my 4 monitors. I was shouting "Go on, please continue!" although it was at a later convenience, not the earliest.

Yes, welcome!. As you know, there 10 kinds of people in the world: those who understand binary and those who don't.

But, of course, hexidecimal is much easier to read.

Reminds me of one of my late Dad's (a proud Irish American) favorite lines.

"There are two kinds of Irishmen. Those that are great singers, and those that think that they are great singers."

(Camron Rust: Thanks for bringing up a great memory of my Dad for me.)

Oh, not this argument again. It has nothing to do with the leading zero problem, except for the demonstration of a null value in the tens place.

Because 0 and 00 are different numbers in the rulebook but the same number mathematically, there's a bit of wiggle room as to how to handle the situation. (For the following notes, I will use an underscore to denote a null value in the tens place.)

• _1 and 01 are equivalent, and both correspond to the player wearing the actual number 1. If a player actually wears 01, that's a technical foul regardless of what they were listed as in the book.
  Neither _1 nor 01 is equivalent to 11. If a player is listed as _1 or 01, and actually wears 11, that's a technical foul.
  _0 and 00 are, by themselves, equivalent, and both correspond to the player wearing the actual number 0 or 00. However, if a team has both an _0 wearing 00 and an 01 wearing 1, or both an 00 wearing 0 and a _1 wearing 1, it's a bit trickier. If I see _0 and 01 (or 00 and _1) in the book, I would remind the coach that 0 and 00 are different numbers, but not consider it a technical foul.

As mentioned in my signature, I am not an official, but I've been on this forum long enough to know the relevant rules.
