It's not just digits. Nobody is expecting it to understand language yet but the parser is-number still returns true for "2e3" or "0x0F". It tells you whether the string can be interpreted as a real numeric value.

Yeah, hence is-"number". But we were talking about regex are we. A number representation can use digits but it can also not. Much like how you make a number using the word "elf".
