Check a specific number and change it

[KM1996 (Kavita)]

Hi UiPath community!

I would really appreciate some help with the following issue:
I have a number (Eg: 151), and I have to check two things:

• Is it a three digit number?
• Does it start with “1”?

If yes to both those conditions, I have to replace the first “1” with “0”. Thus, “151” should be changed to “051”. Unfortunately, I cannot simply subtract 100 from the number as the result will be “51”. Are there any other ways to do this? Can anyone help me with this?

Thanks!

Hi,

If your variable type is Int32, the following will work.

System.Text.RegularExpressions.Regex.Replace(intVar.ToString(),"^1(?=\d\d$)","0")

If your variable type is string, can you try the following?

System.Text.RegularExpressions.Regex.Replace(text,"^1(?=\d\d$)","0")

Thank you so much for your swift response! I tried both methods, and they worked perfectly!

Is there a way I could check for the conditions I mentioned in the post? I need to use a Flow Decision in the workflow!

We can use IsMatch method as the following.

System.Text.RegularExpressions.Regex.IsMatch(intVar.ToString(),"^1(?=\d\d$)")

This expression returns true if intVar start with 1 and has 3 digits.
