15C program question - John Nelson - 06-06-2007

I was looking at the programs we have here, and in the longer quadratic program, it lists a command that I am not familiar with.

026 RCL: 1

I understand the RCL and the 1, but what does the colon signify and how do I enter that on the 15C?

Re: 15C program question - Valentin Albillo - 06-06-2007

It probably is a "division" operation, so just press the RCL key, the division key, and the "1" key.

Best regards from V.

Thanks... that's odd... normally you will see / for division.

Thanks again for the heads up.


Re: 15C program question - Donald - 06-06-2007

is it RCL <decimal point> 1 i.e. RCL 11 ?




Re: 15C program question - John Nelson - 06-06-2007

No... it is a colon.


Re: 15C program question - Egan Ford - 06-06-2007

If you are referring to http://www.hpmuseum.org/software/15cquad.htm then it should be RCL/, not RCL:.

Register 1 contains 2a, so RCL/ 1 is required to get the correct answer.




Re: 15C program question - John Nelson - 06-06-2007

Well, I treated the colon as a divide, so it really wouldn't matter. Is there something else the colon can stand for as I have seen it before, but then a few lines below I would see them use the forward slash so it was as if they were using it interchangeably, which does not make any sense.

As Valentin and others have stated, I think it's supposed to be "divide". The original intent was probably to superimpose ":" on "-", to make a divide sign. A capital theta can similarly be formed by superimposing "-" on a "0".
