正则表达式匹配超过1个小数点

Question

I am trying to support the following formats:

11.11

01.67

30.03

11.45.23

But the Regex i used "/^[+-]?([0-9]*\\.?[0-9]+|[0-9]+\\.?[0-9]*)([eE][+-]?[0-9]+)?$/" supports only first 3 formats.

I need to match numbers with 1 or more decimal points like 11.12.36

Please help me out!

Answer 1

Try this.

sPattern = @"^\d{2}\.\d{2}(\.\d{2})*$";

it will include all numbers

11.11

23.45.57

12.54.78.78

Answer 2

If you want to allow any number of digits between your decimal points and any number of decimal points including a possible starting decimal point you could try something like:

\.?\d+(?:\.\d+)*

This will allow things like .123 123.123 123.123.123.123 etc
