If and only if the number is a code point with the property \pN , than a number other than the number, is any point in the code that is deprived of the specified property, which writes \pN for.
Some regex dialogues pusillanimously insist on hugging them like \p{N} or \p{N} is a bunk, but you are a captive of your language designers of moods and weaknesses, insecurity, or ignorance.
In these dialects of regex with a more readable tilt, you can write them in a more liberal and more legible way, like \p{Number} and \p{Number} respectively.
If you mean a decimal number that does not match a number, you can write it as \p{Nd} , with its complement, therefore, \p{Nd} . The clear version is \p{Decimal_Number} and \p{Decimal_Number} . In some programming languages, this is what means reducing the usability of \d regex.
