Use of regex and decimal points

Dear Team,
Need help which is mentioned below:

  1. How can we fix 2 points after decimal in decimal field type
  2. How can we fix any id of 9 characters, which is combination of alphabets and digits. like..HHS123XYZ
    is there any sample form for that or and article.

Hi @ravird4!

Your best bet might be to try any of the free online regex builders: regex builder - Google Search.
I love - you can paste your own data (much easier than trying to describe to us here), you can build your own regex, and get a free explanation with links to the reference manual immediately, and you can see immediately whether your regex does what you want or not.
