NAME
Mango::BSON::Number - Numerical types
SYNOPSIS
useMango::BSON;useMango::BSON::Number;my$number= Mango::BSON::Number->new(666, Mango::BSON::INT64);say$number;
DESCRIPTION
Mango::BSON::Number is a container for numerical values with a strict type.
METHODS
Mango::BSON::Number inherits all methods from Mojo::Base and implements the following new ones.
new
my$number= Mango::BSON::Number->new(3.14, Mango::BSON::DOUBLE);
Construct a new Mango::BSON::Number object. Croak if the value is incompatible with the given type. The 3 supported types are DOUBLE, INT32 and INT64.
TO_JSON
my$num=$obj->TO_JSON;
Return the numerical value.
to_string
my$str=$num->to_string;
Return the value as a string.
isa_number
my$flags= Mango::BSON::Number::isa_number(25);
Determine if the given variable is a number by looking at the internal flags of the perl scalar object.
Return undef if the value is not a number, or a non-null value otherwise. This value contains flags which can be used for finer analysis of the scalar.
guess_type
my$mongo_type= Mango::BSON::Number::guess_type(25);
Chose which BSON type to use to encode the given numeric value. Possible types are: Mango::BSON::DOUBLE, Mango::BSON::INT32 or Mango::BSON::INT64.
Return undef if the given value is not a number.
OPERATORS
Mango::BSON::Time overloads the following operators.
bool
my$bool= !!$num;
stringify
my$str="$num";
Alias for "to_string".
