NAME

6       Mango::BSON::Number - Numerical types
7

SYNOPSIS

9         use Mango::BSON;
10         use Mango::BSON::Number;
11
12         my $number = Mango::BSON::Number->new(666, Mango::BSON::INT64);
13         say $number;
14

DESCRIPTION

16       Mango::BSON::Number is a container for numerical values with a strict
17       type.
18

METHODS

20       Mango::BSON::Number inherits all methods from Mojo::Base and implements
21       the following new ones.
22
23   new
24         my $number = Mango::BSON::Number->new(3.14, Mango::BSON::DOUBLE);
25
26       Construct a new Mango::BSON::Number object. Croak if the value is
27       incompatible with the given type. The 3 supported types are "DOUBLE",
28       "INT32" and "INT64".
29
30   TO_JSON
31         my $num = $obj->TO_JSON;
32
33       Return the numerical value.
34
35   to_string
36         my $str = $num->to_string;
37
38       Return the value as a string.
39
40   isa_number
41         my $flags = Mango::BSON::Number::isa_number(25);
42
43       Determine if the given variable is a number by looking at the internal
44       flags of the perl scalar object.
45
46       Return "undef" if the value is not a number, or a non-null value
47       otherwise.  This value contains flags which can be used for finer
48       analysis of the scalar.
49
50   guess_type
51         my $mongo_type = Mango::BSON::Number::guess_type(25);
52
53       Chose which BSON type to use to encode the given numeric value.
54       Possible types are: "Mango::BSON::DOUBLE", "Mango::BSON::INT32" or
55       "Mango::BSON::INT64".
56
57       Return "undef" if the given value is not a number.
58

OPERATORS

60       Mango::BSON::Time overloads the following operators.
61
62   bool
63         my $bool = !!$num;
64
65   stringify
66         my $str = "$num";
67
68       Alias for "to_string".
