Significant Digits Problem

[doofusboy]

In searching this site I found the following 2 formulas which I had hoped would be the solution to my problem.

=IF(A2="","",ROUND(A2,2-(1+INT(LOG10(ABS(A2))))))
=TEXT(A2,"0.0E+00")*1

Both work great in displaying an entered value of .981 as 0.98 (2 significant digits)

However, if a value of 1 is entered, I would expect these formulas to display 1.0 (2 significant digits).

I'm assuming the issue is Excel's ever-so-helpful removal of trailing zeros and can be overcome by custom formatting cells to avoid this. The problem I have is the user wants the option to vary significant digits as 2, 3 or 4. Even with custom formatting, I can't get these formulas to show more than 2 significant digits if a value of 1 [or any other whole number] is entered.

Any suggestions?

Another option, with shg's layout ...

The problem with that is that it will truncate significant trailing zeros, pgc. For example, change the input to 1925.008759

Thank you shg. You are right, my formula does not make the precision explicit.

Just for the sake of keeping the formula just at the level of string manipulation, I can change it, like:

=TEXT(TEXT(B$1,"0."&REPT(0,A3-1)&"E+0"),"0"&IF(A3>=FIND(".",B$1),"."&REPT(0,1+A3-FIND(".",B$1)),""))

but it's getting more complex than what I wanted.

That's good but for distinguishing 1930 from 1930. to indicate that the zero is significant.

 

[pgc01]

You are right, a dot in 1900. can indicate that the last zero is significant. It's still not clear in the output the 1900 with 2 or 3 significant digits. Maybe only in vba, like 1900, 1900, 1900 with the non significant digits in another colour. Maybe doofusboy is already happy with the formulas posted.

In B3:

=TEXT(TEXT(B$1,"0."&REPT(0,A3-1)&"E+0"),"0"&IF(A3>=FIND(".",B$1&".")-1,"."&REPT(0,1+A3-FIND(".",B$1&".")),""))

[shg]

Nice work. It avoids the three transcendentals that I used, so should be faster, even it is now equally ooogly

 

[pgc01]

... even it is now equally ooogly

Yes, I was trying to make it a simple solution, but I couldn't.

 

[pgc01]

General reset.

Sorry doofusboy, my formula is wrong (for ex. test it with 0.00987). Today I have no time to be on the board and so I won't be able to amend it.

Use shg's formula. It's a good solution that will solve your problem (unlike mine ).

 

[doofusboy]

Can you explain what you want exactly then?

What I am trying to achieve is this:

Value of .98 entered displays as 0.98 or .98 if 2 significant digits is selected
Value of 1 entered displays as 1.0 if 2 significant digits is selected
Value of 1 entered displays as 1.00 if 3 significant digits is selected
Value of 1 entered displays as 1.000 if 4 significant digits is selected

shg4421's formula:
=TEXT(ROUND(B$1, A3 - 1 - INT(LOG(ABS(B$1)))), "0" & IF(A3 - INT(LOG(ABS(B$1))) > 0, "." & REPT("0", A3 - 1 - INT(LOG(ABS(B$1)))), ""))
seems to achieve this, although I am testing further with other possible entry values to make certain

pgc01's last formula:
=TEXT(TEXT(B$1,"0."&REPT(0,A3-1)&"E+0"),"0"&IF(A3>=FIND(".",B$1&".")-1,"."&REPT(0,1+A3-FIND(".",B$1&".")),""))
is close as it displays 1.0 if 1 is entered and 2 significant digits is selected, but it displays 1.0 if .98 is entered and 2 significant digits is selected

Thanks very much to everyone for their efforts/replies, it is very much appreciated.
