Perl::Critic::Policy::ValuesAndExpressions::RequireNumberSeparators(3)
NAME
Perl::Critic::Policy::ValuesAndExpressions::RequireNumberSeparators -
Write " 141_234_397.0145 " instead of " 141234397.0145 ".
AFFILIATION
This Policy is part of the core Perl::Critic distribution.
DESCRIPTION
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
CONFIGURATION
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!
NOTES
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.
