VERSION

SYNOPSIS

PERL VERSION
13       This library should run on perls released even a long time ago.  It
14       should work on any version of perl released in the last five years.
15
16       Although it may work on older versions of perl, no guarantee is made
17       that the minimum required version will not be increased.  The version
18       may be increased for any reason, and there is no promise that patches
19       will be accepted to lower the minimum required perl.

METHODS
22   valid_args
23         my @args = $type_class->valid_args(@_);
24
25       If the arguments to "valid_args" are valid arguments for this type of
26       tolerance, this method returns their canonical form, suitable for
27       passing to "construct".  Otherwise this method returns false.
28
29   construct
30         my $object_guts = $type_class->construct(@args);
31
32       This method is passed the output of the "valid_args" method, and should
33       return a hashref that will become the guts of a new tolerance.
34
35   parse
36         my $tolerance = $type_class->parse($string);
37
38       This method returns a new, fully constructed tolerance from the given
39       string if the given string can be parsed into a tolerance of this type.
40
41   number_re
42         my $number_re = $type_class->number_re;
43
44       This method returns the regular expression (as a "qx" construct) used
45       to match number in parsed strings.
46
47   normalize_number
48         my $number = $type_class->normalize_number($input);
49
50       This method will decide whether the given input is a valid number for
51       use with Number::Tolerant and return it in a canonicalized form.
52       Math::BigInt objects are returned intact.  Strings holding numbers are
53       also returned intact.  Strings that appears to be fractions are
54       converted to Math::BigRat objects.
55
56       Anything else is considered invalid, and the method will return false.
57
58   variable_re
59         my $variable_re = $type_class->variable_re;
60
61       This method returns the regular expression (as a "qr" construct) used
62       to match the variable in parsed strings.
63
64       When parsing "4 <= x <= 10" this regular expression is used to match
65       the letter "x."
