+=head1 NAME
+
+Perl::Critic::Policy::ValuesAndExpressions::RequireNumberSeparators - Write C< 141_234_397.0145 > instead of C< 141234397.0145 >.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 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
+
+=head1 CONFIGURATION
+
+The minimum absolute value of numbers that must contain separators can
+be configured via the C<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!
+
+=head1 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.
