Remove the last element of a string

For example, I have 0.14V, and I want 0.14.

Browse around in the String Palate for the answer.

Hi mshask,

For example, I have 0.14V, and I want 0.14.

Several options:

1. Get the string length. Get the string subset with length-1…
2. Reverse the string. Get the subset from offset=1. Reverse the string again…
3. ScanFromString a float number. FormatIntoString that number…
4. FractionalStringToNumber, followed by NumberToFractionalString…

It's a nice task to learn about all those string handling functions!

Pretty simple if you use these three functions:

String to Byte Array (turns string into array)

Delete From Array (deletes last element of array by default)

Byte Array to String (array back to string)

5. Match Pattern (use ".$" as pattern, and use the before string).

6. Match Regular Expression (use ".$" as pattern, and use the before string).

7. Match Regular Expression (use "(.*).$" as pattern, extract and use the submatch 1).

8. Search and Replace String (set to Regular Expression, use ".$" as search string).

1. is probably the easiest answer, but you probably want a number. The first part of 3. and 4. make most sense.

If the pattern gets more complex, 3. and 4. become more attractive. If it gets way more complex, 5. .. 8. could be required.

Not exactly duplicate, but still most likely an unnecessary waste of (our) time resources:

Yes, both ask the wrong question (remove the extra letters instead of getting the numbers! :D) and don't really specify the desired result (still a string but with fewer characters? A numeric datatype?)
