How to find the length of a number in labview?

[pmg08]

Hi All,

I am Pramod from Bangalore.

I needed to know is their any VI which calculates the length of a number.

For example, for the number 1000, length is 4. Similary i need it to be calculated automatically in VI, instead of entering manually.

Regards,

Hi pramod,

                 See the attached VI.You can use this as a sub VI.

For integer numbers you could convert number in string (for example format into string using %d in format) and get string length

What about 1.23 or 1,23 as input?  The length could be 1 or 2 or 3 or even 4.

If I understand you right, the input is restricted to positive integers. (if you allow negative numbers, zero, or fractions, you need to define what results you want).

For positive integers inputs, here's a mathematical solution (but the formatting solutions above are probably simpler). 😄

If the number is in a control or indicator, you can do it like this:

I wouldn't account that as solution for floating point numbers. It will only depend on the selected display format and has almost nothing to do with the actual number.

e.g 1.0 with a display format of 10 digits after the comma will result in 12. Doesn't seem very useful to me.
