Discussion Overview

The discussion revolves around how to obtain decimal answers from the HP50G calculator, particularly when it defaults to displaying results in fractional form. Participants explore various methods and settings related to the calculator's operation in scientific mode and its handling of division.

Discussion Character

  • Technical explanation, Debate/contested, Meta-discussion

Main Points Raised

  • One participant expresses difficulty in getting the HP50G to provide decimal answers, noting that it often displays results as fractions instead.
  • Another participant suggests using reverse Polish notation (RPN) for division, but the original poster indicates this does not resolve the issue.
  • A later reply mentions that switching to CAS mode and selecting "approximate" can yield decimal answers.
  • One participant points out a preference for the HP35s, which defaults to decimal results, contrasting it with the HP50G's behavior.
  • Another suggestion is to use the right-shift key followed by enter to convert results to decimal, with a note about switching modes affecting subsequent calculations.
  • One participant proposes dividing the fraction by 1.0 as a method to convert it to decimal form, referencing a similar approach on the TI-89.
  • Another participant mentions that adding a decimal point to one of the numbers in a division operation can also result in a decimal output.

Areas of Agreement / Disagreement

Participants present multiple methods to achieve decimal results, but there is no consensus on a single best approach. The discussion includes various opinions and experiences with the HP50G and comparisons to other calculators.

Contextual Notes

Some participants rely on specific modes and commands that may not be universally applicable, and there are references to different calculator models that may affect the relevance of suggested solutions.

Hi,

I can't seem to get the HP50G to give answers in decimal regularly.

I'm in scientific mode but for instance can only get 13750/119 to appear as 13750/119...

This happens every once in a while and I can't find a command like on the Ti84+ that will force a decimal out of it...

Any help appreciatted,

Can't you get it to just do plain old division? I haven't used an HP calculator for a long time, but the last one I had used reverse Polish notation (RPN). If that's what yours uses, you can get it to do division something like this:
13750 [Enter]
119 [Divide]

Nope,

Give the same result...

I found that Mode>CAS and selecting "approximate" gives a decimal answer.

You'd think that the calculator would be smart enough to know that if your using scientific you'd probably shy away from fractions...Or at least have a quick command to convert.

This is why I like the HP35s. It defaults to decimals but if you enter .26.567 the display is 26/567

Use: [right-shift] [enter] to convert to decimal. Please note that if you press and hold the [right-shift] key, you will actually switch modes from exact to approximate (so that all subsequent calculations are converted to decimals). This can be toggled and you should see the top of your display change from [tex]\approx[/tex] to [tex]=[/tex]
 
Maybe once you get the answer in fraction form, try dividing it by 1.0 That works on my TI-89 when it spits a fraction back at me and I want it in decimal form.
 
When the calculator is in exact mode you can also put a . at the end of one of the numbers and it will give you a decimal. For example type 2. [enter] 5 [divide]
