Defined in header <fkYAML/node.hpp>

fkyaml::basic_node::float_number_type

using float_number_type = FloatNumberType;

The type used to store boolean node values.
The YAML specification describes a floating point number as a type which differentiates the following literals:

  • .inf, .Inf, .INF -> an infinite number
  • .nan, .NaN, .NAN -> Not a Number

To store floating point number objects in basic_node class, the type is defined by the template parameter FloatNumberType which chooses the type to use for floating point number objects.
If not explicitly specified, the default type double will be chosen.
With the decided type, floating point number objects are stored directly inside a basic_node.

Example 
#include <iomanip>
#include <iostream>
#include <type_traits>
#include <fkYAML/node.hpp>

int main() {
    std::cout << std::boolalpha << std::is_same<double, fkyaml::node::float_number_type>::value << std::endl;
    return 0;
}

output: 

true
