I need a pattern for only Numeric & dot.
Eg : 120 / 120.03 / -123.03 / 0.32 whole number and decimal digits are user defined.
Whole numbers & decimals may less then the user defined. Thanks in Advance.

  • @PM77-1 , in the specified case, if user defined decimal was 3 then it should allow upto 3. Eg : 3 / 3.1 / 3.11 / 3.111. how to resolve this. – gnk Feb 03 '16 at 07:13
  • Thank you all. got the pattern based on above. I used "^[-+]?(\d{1,4})(\.\d{1,4})?$". – gnk Feb 03 '16 at 07:36
