A quick, simple and possibly dumb question on the 50g Message #1 Posted by Ken Ratkevich on 19 Oct 2007, 12:39 p.m. Hi, I'm in the middle of writing a term paper and trying to get it in under the wire or else I would scan the manual for the answer. My 50g rounds off base conversions AND, when I switch to engineering notation it does some extreme rounding off. What config do I need to change and how? Thanks in advance for any and all replies, Ken

Hope this helps, Regards, Jandro

Re: A quick, simple and possibly dumb question on the 50g Message #3 Posted by Dave Britten on 19 Oct 2007, 2:29 p.m., in response to message #1 by Ken Ratkevich As for the engineering rounding issue, press Modes, then check the Number Format details. You'll probably see something like Eng 8, with the number representing the number of decimal places. Change that number as necessary. (Note that I'm referring to my 48GX at the moment, so the 50g might look a little different in regards to menus).

Wrong how? Example? How are you doing the conversion?

Re: A quick, simple and possibly dumb question on the 50g Message #7 Posted by Ken Ratkevich on 19 Oct 2007, 5:41 p.m., in response to message #6 by Dave Boyd 1. RS BASE and set to decimal 2. LS #FFFFh (using ALPHA properly) 3. ENTER 4. Result is #65535d. Yeah! 5. Key in #FFFFFh 6. Enter 7. Result is #65535d. Huh? Ken

Re: A quick, simple and possibly dumb question on the 50g Message #8 Posted by Dave Britten on 19 Oct 2007, 5:32 p.m., in response to message #5 by Ken Ratkevich Try checking your word size: RCWS If it's only 16, then there's your answer. To change the word size (bit length) for base operations, use STWS, e.g. 32 STWS. You can do anywhere from 1 to 64 bits, I believe.
