minilua::Number class

Numbers in lua can be integers or floats.

The Number type automatically converts Int to Float according to the rules of lua.

The equals and hash implementation treat whole Floats and like their equivalent Ints.

Supports comparison operators and +, -, *, /, ^ (exponentiation), %, &, |.

Is hashable.

Public static variables

static static const std::string_view TYPE constexpr: The type of this value as a string.

Number(int value) constexpr: Creates a number form an int.
Number(Int value) constexpr: Creates a number form a Int.
Number(Float value) constexpr: Creates a number form a Float.
operator bool() const explicit: Convert the value to a bool (always true).

auto to_literal() const -> std::string -> auto: Converts the value to it's literal representation.
auto as_float() const -> Float -> auto: Converts the number to a float.
auto try_as_int() const -> Int -> auto: Returns the number as an int if it is a whole number.
auto convert_to_int() const -> Int -> auto: Convert to Int.
auto is_int() const -> bool -> auto: Check if the number is an int.
template<typename Fn> auto apply_with_number_rules(const Number& rhs, Fn fn) const -> auto: Invoke the given function with either two Ints or two Floats.

Converts the number to a float.

If it is an int otherwise just returns the number.

Returns the number as an int if it is a whole number.

Exceptions
std::runtime_error

Otherwise throws an exception.

Convert to Int.

By casting the Float to an Int (if it is not already an Int).

Invoke the given function with either two Ints or two Floats.

If one of the numbers (either this or rhs) is a Float the other one will also be converted to a Float if it is not one.
