I used to have an usb cd drive, but nowadays plan9 is the only thing I have which fits on one cd and thus I stopped using this medium. On Wed, May 20, 2009 at 1:21 AM, Francisco J Ballesteros wrote: > Is anyone using usb cdroms? (with other systems, I mean). > Just curious. > > On Wed, May 20, 20

Uh, thanks for the reply. Now that I think about it endianness was the obvious reason behind this. Saludos 2009/5/20, erik quanstrom : > On Wed May 20 06:57:14 EDT 2009, uai...@gmail.com wrote: > > I have an xd(1) question. Am I wrong or xd gets the byte ordering wrong? > > > no. xd is correct.

I have an xd(1) question. Am I wrong or xd gets the byte ordering wrong? 1. While working on native plan 9 I always got the opposite byte ordering from what I expected. 2. xd output from p9p shows exactly the opposite byte ordering that hexdump output. Perhaps there's something wrong with xd. -- H

2009-05-20 Thread Jonas Amoson
Hello Hugo, Done some experiments with the indivudual bits in Lunix, and would be very surprised if it is not handled the same under Plan 9, given the same hardware architecture. The exponent is stored in base 2, but What might be a bit confusing, is that it is not stored using two's complement,

[9fans] plan 9 floating point representation

2009-05-20 Thread hugo rivera
Hi, I am learning a bit about floating point representation and I am wondering about how plan 9 does this. According to IEEE 754 (I think) the convention used by C for single precision floating point numbers is to use 24 of the 32 bits available for the significand and 8 bits for the exponent. It s
