Integer Type Utilities

This section presents the utility types for determining the correct integer type for a given bit-width.

Base Templates

template <int Size>
struct int_for_size

A template to determine the exact int type to represent the given size.

This template provides integer types that match the given size exactly. If a given size can be represented exaclty, it provides a member type called type that is an alias for the repective integer type.

See

avr::uint_for_size For the equivalent helper for unsigned types

Since

1.0.0

Template Parameters

• Size: The desired size of the type

template <int Size>
struct uint_for_size : public make_unsigned<int_for_size_t<Size>>

A template to determine the exact unsigned int type to represent the given size.

This template provides unsigned integer types that match the given size exactly. If a given size can be represented exaclty, it provides a member type called type that is an alias for the repective integer type.

avr::int_for_size For the equivalent helper for signed types
