## Convert 2D string array to 2D number array.

Hello,

I have the following problem. I need to convert a 2D string array to a 2D number array. My array exists out of 2 columns and x rows. So what I first did was this. Just splitted the array in two parts for each column. At that moment I had two 1D arrays next I converted it with a solution I found here at the forums. It works perfectly only isn't there a way to convert a 2D string array to 2D number array. I myself tried several things but unfortunaly I didn't manage. Anyone can help?

Thanks in regards,

- Wouter

## Re: Convert 2D string array to 2D number array.

You don't need aything special, the string/number conversion tools take arrays of any dimension. 🙂

## Re: Convert 2D string array to 2D number array.

You should use nested for loops and the Decimal String to Number.vi in the inner for loop, and use auto indexing coming out of each for loop to rebuild your array.  See the attached vi for an example.  Or use Altenbach's method as I suppose I should have advised you to do as well.

Cheers!

## Re: reconstract string with hex string

Hi soliman,

the problem is you didn't provide any default data in your controls nor did you really describe what you want ("hex string with lingth of 4 as (503D XX54)" - that's a length of 9 chars for me...).

There's a difference between a string in hex display mode or hex numbers or simple strings! But that has been discussed so often in the forum you could easily find threads discussing your question... (Why the hell you're using mathscript to convert a number to a different number?)

In the meantime you may play with that:

## Re: Convert 2D string array to 2D number array.

Hello, if you are still responding to this thread...I have a question.  How do you extend the significant digits to the number array?  I am trying to retain the forth number down in the attached array of text files: 15.0.txt - including the decimal ".0" after the 15.  The result I get is just ("15").

## Re: Convert 2D string array to 2D number array.

I am not sure what you want to achieve here (maybe a VI would help ?) but have you tried to play with the array Display Format ? Right click on it and see what's available 😉

## Re: Convert 2D string array to 2D number array.

Hi Newton,

what about a better format string when creating those filenames?

Maybe "%.7f" would help!?
