convert string to float

[Tamas]

Hi,

I would like to convert string to float. I have an text file which contents string float number.

for example:

10.000   2. 0000  1.32323 these strings I would like to convert float or double number.

Please help!

You can use "format into string"

[Kumar_B]

Use "Fract/Exp String To Number" function from string palette.  Or while reading from file use "Spreadsheet String To Array" with array type as DBL array.

-Kumar.B

[muks]

"Decimal string to array"

[Hummer1]

I think Kumar is good on this one.  It returns all the digits of the text based number rather than just the intiger portion returned by the other alternative.

I use the spreadsheet string to array vi and I have to set correct the format string.

%.; %f

Thanks everybody!

 Hi guys,

Im trying to convert a string to float number too, but my string comes from a text file and has to be converted to float but i cant make it reconize the (.) divisor. I gonna send a pic of my code. any suggestions.

You don't want Decimal String to Number (which will only give you an integer).  You want Fract/Exp String to Number (which will give you a floating point number).

Yes lol i used it before but the wrong way.. now it works thx. and sory for dumb question... its to many hours around the program 😄

Looking at the picture, I think you have several more problems than just converting to floating point. I would be happy to look at your code and give some recommendations if you would attach the VI.

• What did you possibly have in mind when doing the "to dynamic...from dynamic" dance in the upper left corner? We cannot see the node configuration, but are you possibly trying to emulate a transpose operation? There are better ways!
• You seem to have a lot of duplicate code that could be combined.
