[Richard]

Is 61_298_040_283_768 and 61298040283768 are same in Perl.

[Riki]

Perl allows underscores for clarity within integer literals, so we can also write that number like this:

61_298_040_283_768
It's the same value; it merely looks different to us human beings. You might have thought that commas should be used for this purpose, but commas are already used for a more-important purpose in Perl
