This module contains type aliases for memory data units. According to the
official standard, there exist two naming conventions for memory units. Standard
measure prefixes are multipliers of 10
. But there are alternative prefixes
which end with bi
and they are represented as powers of 2
. The difference
can be displayed in the following table:
Name | Multipliers | In bytes |
---|---|---|
Kilobyte | \( 10 ^ 3 \) | 1000 |
Kibibyte | \( 2 ^ {10} \) | 1024 |
Megabyte | \( 10 ^ 6 \) | 1000000 |
Mebibyte | \( 2 ^ {20} \) | 1048576 |
