Perl::Critic::Policy::ValuesAndExpressions::RequireNumberSeparators - Write " 141_234_397.0145 " instead of " 141234397.0145 ".
This Policy is part of the core Perl::Critic distribution.
Long numbers can be difficult to read. To improve legibility, Perl allows numbers to be split into groups of digits separated by underscores. This policy requires number sequences of more than three digits to be separated. $long_int = 123456789; #not ok $long_int = 123_456_789; #ok $long_float = 12345678.001; #not ok $long_float = 12_345_678.001; #ok
The minimum absolute value of numbers that must contain separators can be configured via the "min_value" option. The default is 10,000; thus, all numbers >= 10,000 and <= -10,000 must have separators. For example: [ValuesAndExpressions::RequireNumberSeparators] min_value = 100000 # That's one-hundred-thousand!
As it is currently written, this policy only works properly with decimal (base 10) numbers. And it is obviously biased toward Western notation. I'll try and address those issues in the future.
