A program to toggle between prefixes
hi everybody,

I need an easy way to toggle between prefixes (a,f,p,n,µ,m ... k,M,G,T,P,E) and write them after a number.
For example:
I have 0.135 and I would like to toggle: 135 m, 135000 µ, 135000000 n ...
or I have 135000 and I would like to toggle 135 k, 0.135 M, 0.000135 G and so on...
This purpose having or not having regard to the unit of measure (i.e. V, F, ohm...), like in some Casio calculator (with the ←ENG and ENG→ buttons)...
I mean to toggle back and forward from any number in a simple way (like with user keystrokes or other way with *very few* keystroke pressing)...

Any idea?

RE: A program to toggle between prefixes
That sounds like it would be very useful to have.

Perhaps some of the code in my Z UNITS program will inspire someone to find a good solution.

That program supports prefixes, but as it stands it's not what you want:
1 - it is a standalone program (so you'd need to retype your number)
2 -- it is unit specific.

So, as it stands, the program should let you convert, say,
3*MEGA V to V (with my program recognising MEGA as a numerical value)
..but will only do the reverse
3 V to MV
If MV is a calculator-supported unit conversion.

But perhaps there is something in there that will help towards a better solution.

Hi Stephen,
I'll see the code in your program, thank you.

Update: checked, but I get error at line 224...

I can't see line numbers on my Android, but at a guess that is a long line...
I have seen an issue before with cut and paste putting in the occasional wrong kind of Unicode space. Just deleting the space or deleting it and retyping it will probably make the error go away.

If that doesn't help, there is a slightly older version of Z UNITS within an old version of ZIPP - you could try that.

maybe the error is about here
Code:

REPEAT

   OK:=CHOOSE(CHS,WDATAU(SL)+SG,DATATYPES(SL));
   IF OK THEN
    LBL:={WVALU(SL),WPREFIX(SL),DATATYPES(SL,CHS),"2^",WSOLVE(SL)};
    CASE
     IF CHS==1  THEN //CAPACITY
      OK:=INPUT({VALU,{PFX,PFXS},{QTYU,QTYTP},{USEBIN,1},{SLV,1}},TTL(1),LBL,HLP3​​(SL),1,1);
      IF OK THEN
       PFXNSTEP:=IFTE(USEBIN,2^10,10^3);
       PFXN:=IFTE(USEBIN,2^(10*(PFX-1)),1000^(PFX-1)); 
       IF SLV THEN //B=BPS*S
        VBITS:=VS*VBPS;
       ELSE
        VBITS:=VALU*PFXN*DATAS(QTYU);
       END;
       VALUES:=VBITS/{DATAS};
       MSGBOX(VALUES); 
       VALUES:=VALUES(1);//UNLIST?
       REPEAT 
        OKC:=CHOOSE(NC,"",QTYTP);
        IF OKC THEN       
         NUM:=VALUES(NC);
         ST:="";
         FOR II FROM  1 TO SIZE(PFXS) DO
          ST:=ST+(NUM/(PFXNSTEP^(II-1)))+PFXS(II)+QTYTP(NC)+NL;
         END;
         MSGBOX(ST); 
        END;
       UNTIL OKC==0;

      END;
     END;

Better, I need something between your Z Units program and this ENG program (ENG) to toggle ENG powers and prefixes...

I just checked it - there are about 6 lines that need changing.
All are spaces that shouldn't be there.
HLP3 (SL) should be HLP3(SL) (three lines, each with a differently positioned space)
a cre should be acre
1_ gal should be 1_gal
1_th erm should be 1_therm

When I download my version to Android, I see those extra spaces...
Hope it helps

RE: A program to toggle between prefixes
For me, that version still has the unwanted visible spaces - or the Android is putting them back in. I find I need to manually edit the 6 lines after downloading.

maybe Android put in again the invisible space, I've pasted here in Mac OS X via Parallels Windows 10, as I do always...

RE: A program to toggle between prefixes
Hi Salvomic,

The scientific notation exponent on base 10 of a value could be matched with the corresponding value in an SI prefix list, and append the prefix abbreviation, or name, on returning corresponding value. I haven't coded a routine for this, but you might have some ideas to expand on this theme. Here is an SI prefix list you might find useful, (omitting 1e0, which could be the default case) :

Code:

SI:={ 1e-24,"y","yocto",
      1e-21,"z","zepto",
      1e-18,"a","atto",
      1e-15,"f","femto",
      1e-12,"p","pico",
      1e-9,"n","nano",
      1e-6,"u","micro",
      1e-3,"m","milli",
      1e-2,"c","centi",
      1e-1,"d","deci",
      1e1,"da","deca",
      1e2,"h","hecto",
      1e3,"k","kilo",
      1e6,"M","mega",
      1e9,"G","giga",
      1e12,"T","tera",
      1e15,"P","peta",
      1e18,"E","exa",
      1e21,"Z","zetta",
      1e24,"Y","yotta"
    };

RE: A program to toggle between prefixes
How about loading the number into a spreadsheet...
And having adjacent cells showing all the alternatives.
Not as easy as a built-in toggle, but it might help.

Apologies for cluttering up so much of this thread with my program.

RE: A program to toggle between prefixes
thank you Dale and Stephen,
I could do something like this code (modifying the program of user cclinus in this post

(this code begin to work like the original "ENG" simulation, that I've modified to handle from E-24 to E24)...
shift-Help / lower "ENG, shift-Help * increase, shift-Help + return the normal number, shift-Help - change "Exx" into prefix...
It's a first attempt...

Code:

// Program to toggle between  ←ENG and ENG→
// define keys / * + (toggle_eng_float)

reeng();

EXPORT ENGA(x)
BEGIN
LOCAL pos,s,i;
IF TYPE(x)==0 THEN
RETURN STRING(x,4,11);
END;

IF (TYPE(x)==2) THEN
  IF (INSTRING(x," ")) THEN x:= reeng(x); END;
END;

IF (TYPE(x)==2) AND (INSTRING(x,"ᴇ24")) THEN
RETURN x;
END;
IF (TYPE(x)==2) AND (INSTRING(x,"ᴇ24")==0) THEN
s:=x;
FOR i FROM 1 TO 3 DO
pos:=INSTRING(s,".");
s(pos):=s(pos-1);
s(pos-1):=".";
IF pos==2 THEN
s:="0"+s;

s:=REPLACE(s,"ᴇ−18","ᴇ−15");
s:=REPLACE(s,"ᴇ−21","ᴇ−18");
s:=REPLACE(s,"ᴇ−24","ᴇ−21");
RETURN s;
END;
END;

EXPORT ENGB(x)
BEGIN
LOCAL pos,s,i;
IF TYPE(x)==0 THEN
RETURN STRING(x,4,11);
END;

IF (TYPE(x)==2) THEN
  IF (INSTRING(x," ")) THEN x:= reeng(x); END;
END;

IF TYPE(x)==2 AND (INSTRING(x,"ᴇ−24"))THEN
RETURN x;
END;
IF TYPE(x)==2 AND (INSTRING(x,"ᴇ−24")==0)THEN
s:=x;
FOR i FROM 1 TO 3 DO
pos:=INSTRING(s,".");
IF s(pos+1)==7431 THEN
s:=REPLACE(s,".ᴇ","0.ᴇ");
ELSE
s(pos):=s(pos+1);
s(pos+1):=".";
IF (pos==2) AND (s(1)==48) THEN
s:=RIGHT(s,DIM(s)-1);
END;
END;
END;
WHILE INSTRING(s,"0ᴇ") DO
s:=REPLACE(s,"0ᴇ","ᴇ")
END;
//
s:=REPLACE(s,"ᴇ−21","ᴇ−24");
s:=REPLACE(s,"ᴇ−18","ᴇ−21");
s:=REPLACE(s,"ᴇ−15","ᴇ−18");

END;
END;

t:=REPLACE(t,"ᴇ18"," E");
t:=REPLACE(t,"ᴇ21"," Z");
t:=REPLACE(t,"ᴇ24"," Y");
RETURN t;
END;

EXPORT reeng(s)
BEGIN
LOCAL t;
IF TYPE(s)==0 THEN t:= STRING(s,4,11); ELSE t:= s; END;

t:=REPLACE(t," P","ᴇ15");
t:=REPLACE(t," E","ᴇ18");
t:=REPLACE(t," Z","ᴇ21");
t:=REPLACE(t," Y","ᴇ24");
RETURN t;
END;

with this code for the user key
Code:

// this require ENGA(), ENGB(), prefix(), reeng() in a program
KEY K_Mul()
BEGIN
RETURN "ENGA(Ans)";
END;

KEY K_Div()
BEGIN
RETURN "ENGB(Ans)";
END;

KEY K_Plus()
BEGIN
RETURN "EXPR(reeng(Ans))";
END;

KEY K_Minus()
BEGIN
RETURN "prefix(Ans)";
END;

But this code need to be modified in three ways:
1. deleting the leading zeroes at the end, i.e. "1.2530000000E9" should be "1.253E9" without zeroes...
2. avoiding to have ENGA(Ans), ENGB(Ans) and prefix(Ans): for a real "ENG key" simulation it would be better don't show them
3. implementing back and forward also for prefixes like in ←ENG and ENG→ of the (modified) original program (if one want to have both systems ENG and prefixes)

Any hints?
