Feature request: support ability to write more readable decimal number literals

[scorpion9979]

E.g., fp("10,000,000.256") is a lot easier to read than fp("10000000.256").

Interesting. The downsides though are that (1) implementing this is not easy and (2) might lead some users to confusion. Some countries use the comma to represent the fractional part and others use the dot.
