Hello, I have a *.txt file and inside it contains lines with information (each block of information in a new line). This information has a similar pattern:
2014.05.26 11:45:00,67.14975845410586

The next lines have the same structure, the difference is the date value and the number's value.

In the above line I want to remove the comma and all the information in the left. About the number I want the integer part and the first four decimals.
Example: 67.1497

I have tried with Trim, Right, Mid... but I cannot code it right.
