Converting string to number

[MarinaNashaat]

Here is a screen shot & VI

[RavensFan]

Neither of your attached VI's have the data saved into the string as a default.  They are still empty.  So I'll look at your screen shot that now shows the string.

The reason is because the function you are using is intended to look for a single number and treat it as a decimal whole number.  You have a space which means the first number has ended.

You need to strip the spaces out of the string before converting.  Then you need Scan from String with %b has the format string.

I want the number to be 1000101011111 not 4447

[RavensFan]

Then change the display format of the numeric indicator to binary instead of decimal.

You dont actually expect a string of "11111111" as a series of 1's in binary to be converted to the number 11,111,111  (11 million +) in decimal, do you?

No 

Iexpect a string of "11111111" as a series of 1's in binary to be converted to the number 11111111  in binary but even after search& replace then scan .. the output is wrong

[Dennis_Knutson]

The output is not at all wrong. Decimal 4447 is equal to binary 1000101011111 which is something basic that you should understand. Whether you display a number in decimal, hex, binary, octal, etc., it's exactly the same number. The display format of a front panel indicator is not going to change the number which is also something basic that you don't seem to understand.

The output is NOT wrong.  Your indicator is set to display decimal.  If you want it to display 1's and 0's, change it to display binary.

Does this make it clearer?
