Lenght of a decimal part of a number.

[Guest]

Hi, I am doing some programming where I need to know the number of digits of
the only decimal part of a number. I ended up with the following equation:

In cell A1 I entered a decimal number.
In cell B1 I wrote the following : =LEN(A1-INT(A1))
this should give me the numbers of the decimal part.

Examples:
A1 B1
100 1
10.25 4
3.2 3
6.7 3
9.2 17 WHY? this my question.

Try

=A5-INT(A5)

copy the result and paste special as values in a cell, now check what you
got

Use

=LEN(ABS(A1))-LEN(INT(ABS(A1)))-(A1<>INT(A1))

instead.

or you could try this

=LEN(TEXT(A5-INT(A5),"#.#####"))-1

Use

=LEN(ABS(A1))-LEN(INT(ABS(A1)))-(A1<>INT(A1))

instead.

Here is a shorter formula which also appears to work...

=MAX(0,LEN(A1)-FIND(".",A1&"."))
