Detailed Description

User-defined literals for binary (base-2) memory units.

These operators provide convenient syntax for expressing memory sizes using binary units (powers of 1024) rather than decimal units (powers of 1000).

Function Documentation

operator""_kib()

decltype(auto) operator""_kib ( unsigned long long value )

inlineconstexprnoexcept

User-defined literal operator for kibibytes (KiB)

Converts a numeric literal to bytes by multiplying by 1024 (2^10). A kibibyte is 1024 bytes, following the IEC 60027-2 standard for binary prefixes.

Parameters

value

The numeric value in kibibytes

Returns

unsigned long long The equivalent value in bytes

Note

This operator is constexpr, allowing compile-time evaluation

Uses bit shifting (1 << 10) for efficiency instead of multiplication

operator""_mib()

decltype(auto) operator""_mib ( unsigned long long value )

inlineconstexprnoexcept

User-defined literal operator for mebibytes (MiB)

Converts a numeric literal to bytes by multiplying by 1,048,576 (2^20). A mebibyte is 1,048,576 bytes (1024 * 1024), following the IEC 60027-2 standard.

Parameters

value

The numeric value in mebibytes

Returns

unsigned long long The equivalent value in bytes

Note

This operator is constexpr, allowing compile-time evaluation

Uses bit shifting (1 << 20) for efficiency instead of multiplication
