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.
