NAME

       Number::Tolerant::Type - a type of tolerance

VERSION

       version 1.710

SYNOPSIS

PERL VERSION

       This library should run on perls released even a long time ago.  It should work on any
       version of perl released in the last five years.

       Although it may work on older versions of perl, no guarantee is made that the minimum
       required version will not be increased.  The version may be increased for any reason, and
       there is no promise that patches will be accepted to lower the minimum required perl.

METHODS

   valid_args
         my @args = $type_class->valid_args(@_);

       If the arguments to "valid_args" are valid arguments for this type of tolerance, this
       method returns their canonical form, suitable for passing to "construct".  Otherwise this
       method returns false.

   construct
         my $object_guts = $type_class->construct(@args);

       This method is passed the output of the "valid_args" method, and should return a hashref
       that will become the guts of a new tolerance.

   parse
         my $tolerance = $type_class->parse($string);

       This method returns a new, fully constructed tolerance from the given string if the given
       string can be parsed into a tolerance of this type.

   number_re
         my $number_re = $type_class->number_re;

       This method returns the regular expression (as a "qx" construct) used to match number in
       parsed strings.

   normalize_number
         my $number = $type_class->normalize_number($input);

       This method will decide whether the given input is a valid number for use with
       Number::Tolerant and return it in a canonicalized form.  Math::BigInt objects are returned
       intact.  Strings holding numbers are also returned intact.  Strings that appears to be
       fractions are converted to Math::BigRat objects.

       Anything else is considered invalid, and the method will return false.

   variable_re
         my $variable_re = $type_class->variable_re;

       This method returns the regular expression (as a "qr" construct) used to match the
       variable in parsed strings.

       When parsing "4 <= x <= 10" this regular expression is used to match the letter "x."
