Function Documentation

operator""_cnl()

template<char... Chars>

constexpr auto cnl::literals::operator""_cnl ( )

constexpr

generate an elastic_scaled_integer object using a literal

Template Parameters

Digits

the characters of the literal sequence

Returns

the given value to be represented using an elastic_scaled_integer type

Note

The return type is guaranteed to be no larger than is necessary to represent the maximum value of Integral.

Example

To define a decimal fixed-point object with value 3.141:

    using namespace cnl::literals;
    constexpr auto n = 3.141_cnl;
 
    static_assert(n == 3.141);
    static_assert(
            std::is_same<
                    elastic_scaled_integer<12, power<-3, 10>> const,
                    decltype(n)>::value);

operator""_cnl2()

template<char... Chars>

constexpr auto cnl::literals::operator""_cnl2 ( )

constexpr

generate an elastic_scaled_integer object using a binary literal

Template Parameters

Digits

the characters of the literal sequence

Precondition

Sequence must be representable using binary fractions. E.g. 0.1_cnl2 cannot be represented using binary fixed-point numbers. This will not compile.

Returns

the given value to be represented using an elastic_scaled_integer type

Note

The return type is guaranteed to be no larger than is necessary to represent the maximum value of Integral.
