no fraction mark in the output of an hp49G+ - Benny Vanrutten - 03-06-2006 On the hp49G+ I like to convert a binary to real:
# 11111000b B->R then I got Thanks a lot.

Re: no fraction mark in the output of an hp49G+ - Tim Wessman - 03-06-2006 Do you want "256." or "256," or "256" ? If you want "256.", clear flag 51. Set flag 51 for "256,". If you want "256" then that is an integer not a real. Run R->I to get a zint.

Re: no fraction mark in the output of an hp49G+ - Benny Vanrutten - 03-06-2006 Thanks Tim, I need 248
Kind regards, Re: no fraction mark in the output of an hp49G+ - Thomas Okken - 03-06-2006 The HP-48 does not distinguish between "real" and "integer" -- I assume the convention of showing reals like "248," even when their fractional part is zero, is something that was added in the 49.

Re: no fraction mark in the output of an hp49G+ - Benny Vanrutten - 03-06-2006 Hi Thomas,
The HP48GX gives the answer I need, but giving the same command to the HP49G+ responds in the value followed by the unwanted fraction mark. Kind regards,
Benny
Re: no fraction mark in the output of an hp49G+ - Crawl - 03-06-2006 The difference between 248 and 248. is important on the 49G+. 248 is the exact number, "Two hundred Forty Eight". 248. is the decimal approximation.
1 divided by 3 = 1/3, the exact fraction.
1. divided by 3 = 0.3333333333, the decimal approximation.
Re: no fraction mark in the output of an hp49G+ - James M. Prange (Michigan) - 03-06-2006 The 48 series has system flags -1 through -64 and user flags 1 through 64. The 49 series has system flags -1 through -128 and user flags 1 through 128. "Exact" versus "approximate" modes are controlled by system flag -105; within a program, clear it for exact mode, or set it for appoximate mode. For interactive use, hold down the RightShift key while pressing the ENTER key to toggle between exact and approximate modes.

Re: no fraction mark in the output of an hp49G+ - James M. Prange (Michigan) - 03-06-2006 The 49 series lacks built-in B->I and I->B UserRPL commands, so converting between these object types are 2-step processes. You could write your own programs: B->I
Regards, Re: no fraction mark in the output of an hp49G+ - Benny Vanrutten - 03-07-2006 Thanks James, That's (B->I) exactly what I added to my program last night.
