I have found a solution for case 1:
^((0[\,\.]000[1])|([1-9]\d{0,3}(?:[\,\.]\d{1,4}))|(?:10000(?:[\,\.]0{1,4})))?$


However, the expression is not as difficult as is said here.
At the special request of a single person, the regular expression now also accepts "." and ",".

I program in QT and QLineEdit can be configured very nicely and effectively with regex expressions. I would therefore be very reluctant to deviate from this.

I am programming an LCR measuring bridge front end from Analog Devices (ADMX2001). The tDelay value range between 0.0000 and 65536.0000 is expected by the frontend and is also checked. And the value range does not fit into a uint16. Should I now discuss the specified value range with Analog Devices ? They must know in which way the bridge operates.
