public enum DecimalSizeUnit extends Enum<DecimalSizeUnit>
This enum defines a set of size units that can be used to represent data sizes in varying units (bytes, kilobytes, megabytes, gigabytes, etc.). This class uses decimal-based values rather than binary-based values, so each unit is 1000 times larger than the previous (for example, one kilobyte is interpreted as 1000 bytes rather than 1024 bytes).

    • bytesToHumanReadableSize

      @NotNull public static String bytesToHumanReadableSize(long numBytes)
      Retrieves a string that represents a human-readable representation of the specified number of bytes. The string representation will be constructed in accordance with the following rules:
      • The string representation will use the abbreviation for the unit (e.g., "b" instead of "bytes", "KB" instead of kilobytes, etc.)
      • If the provided value represents an exact multiple of the number of bytes for a given unit, then the string representation will be an integer followed by the abbreviation for the unit (e.g., a value of 123 will result in a string representation of "123b", a value of 524880 will result in a string representation of "5MB", a value of 7516192768 will result in a string representation of "7GB", etc.).
      • If the provided value does not represent an exact multiple of the number of bytes for the given unit, then the string representation will use a floating-point number with two digits behind the decimal point. It will select the unit so that when possible, there will be between 1 and 3 digits before the decimal point (e.g., a value of 12345 will result in a string representation of "12.06KB", a value of 9876543210 will result in a string representation of "9.20GB", etc.).
      Parameters:
      numBytes - The number of bytes to represent as a human-readable size. It must be greater than or equal to zero.
      Returns:
      A string that represents a human-readable representation of the specified number of bytes.

    • bytesToHumanReadableSize

      @NotNull public static String bytesToHumanReadableSize(@NotNull BigInteger numBytes)
      Retrieves a string that represents a human-readable representation of the specified number of bytes. The string representation will be constructed in accordance with the following rules:
      • The string representation will use the abbreviation for the unit (e.g., "B" instead of "bytes", "KB" instead of kilobytes, etc.)
      • The string representation The string representation will use the abbreviation for the unit (e.g., "B" instead of "bytes", "KB" instead of kilobytes, etc.)
      • If the provided value represents an exact multiple of the number of bytes for the selected unit, then the string representation will be an integer followed by the abbreviation for the unit (e.g., a value of 123 will result in a string representation of "123B", a value of 524880 will result in a string representation of "5MB", a value of 7516192768 will result in a string representation of "7GB", etc.).
      • If the provided value does not represent an exact multiple of the number of bytes for the selected unit, then the string representation will use a floating-point number with two digits behind the decimal point (e.g., a value of 12345 will result in a string representation of "12.06KB", a value of 9876543210 will result in a string representation of "9.20GB", etc.).
