How do you convert decimals to fractions?
Is there anyway to reduce the autopower off time? It's too long.
How do you erase all of the data (all of the previous calculations and notebook stuff)?? I think it is slowing my calculator down.
Thanks!

If you'd like to change the auto timeoff, store a hexadecimal number in a value named TOFF in your home directory. #(sec*8192)d is the number, so for 15 seconds, it would be #122880d (15*8192). Default time is 5 minutes I think. TW

First off, be sure to have the HP 49g+ & 48gII_Advanced
Also have a look at the Quote:Of course, for an exact conversion, you could consider the "real" (decimal) number to be the numerator of a fraction with 1 as its denominator, and multiply both the numerator and denominator by whichever is the lowest power of 10 required to make the resulting numerator an integer.
Other than that, for approximate conversions, you could try the
Also try searches of http://www.hpcalc.org/ and
Maybe read the training module entitled Working with Quote:Yes. With any 49 series, store a binary integer up to #FFFFFFFFh (the largest 32bit integer) in the reserved variable 'TOFF'. This represents the number of ticks (1 second = 8192 ticks) of inactivity before the calculator automatically turns off, with a minimum of 5 seconds as a "safety net". For example, storing #5A000h in TOFF results in a 45second automatic timed OFF.
For a "neveroff" mode, an alternative is to store a program that Quote:?????
Do you mean how to clear the stack? RightShift CLEAR does that. Of
If you mean how to purge variables, you can use the PURGE (or for
To clear memory entirely, press and hold [ON], [A], and [F] all
Of course, all of this assumes that you have the 49 series in
Last but not least, for RPL models, you'd probably do better
