Also, if you use the library functions for parsing floating point values, they will/may consider the culture. In many European cultures, a decimal comma is used, not a decimal point. The point is used a digit group separator.

Programming code literals (almost?) always follows the English tradition of decimal point, and comma as group separator. User input is different. You can't make all users switch to a different number syntax just because your program doesn't honor the local culture.

A minor non-regex comment to the OP: If you intend the check
C++
Case 2. (ui >= 0.0000) & (ui <= 65536.0000)
to verify that the number can be converted to a 16 bit uint, then it should be either (ui < 65536.0000) or (ui <= 65535.0000).

(But then, I think it curious to verify a floating point number against the value limits of an integer type. A numeric value is either a measurement or a count. Re-interpreting a measurement as a count is a strange thing to do.)

Religious freedom is the freedom to say that two plus two make five.
