how can I do the conversion from a string to a float

[larche]

Hi,
I need to take a string, which is the time and to convert it into a float, because the program I send it to is only receiving a float...how can I do that?

[cschneider]

In the strings-palette, there's a subpalette called "String/Number"-conversion...Just use Fract/Exp-String to Number to convert your string GreetingsChristian

It may not be as simple as that. Is the string simply the float value as a string (in which case you can do the above), or is it in a specific format?

let me explain, if the time is the string 18;30;36 I want the float 183036 kind of

well assuming the time is broken up by semicolons as you have shown,first, split up the time, using ";" as your split character.then, you have three segments: hours, minutes, seconds.
Then i would convert each of those (using string --> dbl or something like that)
Then you have 3 numbers to do whatever you would like with.

There can be different approaches, just two of them: Use Scan from String to get the different parts of your string as Number or eliminate your ;;; from your string with "Search and replace string"...

Heres the program that I was describing earlier (and accidentally posted twice oops)

My contribution to the conversions...gives you a 1D array of 3 elements (one for each section of the string).<img src="Loading Image..."> Message Edited by corys on 08-07-2008 03:14 PM

Yeah, smercurio, I think so...that's why I posted that solution...

Scan From String is a lot easier, don't you think? :smileywink:

[Cory K]

Well, I just created the first method that came to mind.
Yes scan from string is a lot simpler, and less work.....either one works.
Actually, there are probably 10 other ways to do it, up to you.

[larche]

thanks for all the solutions, but I didn't explain well...sorry
I have three different boxes, one for each part of the string, one for the hours,one for the&nbsp;minutes and one for the seconds.
At the end, I want just one number, which will group the time together, example: 043006

Something like this?<img src="Loading Image..."> Message Edited by corys on 08-07-2008 03:23 PM

yes exactly and if it's 4 o'clock for example, I want 04

This seems like it has to be some Rube Goldberg code, but here's one way of doing it. (Note: The display format for the numeric indicator must be changed as shown in the picture, or else zeros before the hour will not show).<img src="Loading Image..."> <img src="Loading Image..."> Message Edited by corys on 08-07-2008 03:44 PM
