Class Method Details

.convert_binary(n) ⇒ Object

Converts a number to binary byte units and outputs with the IEC prefix For example,

LinuxStat::PrettifyBytes.convert_binary(1000) # => “1000.0 bytes” LinuxStat::PrettifyBytes.convert_binary(1000 ** 3) # => “953.67 mebibytes” LinuxStat::PrettifyBytes.convert_binary(1024 ** 3) # => “1.0 gibibyte”

	converted = n.fdiv(unit[1] / 1024).round(2)
	"#{pad_left(converted)} #{unit[0]}byte#{?s.freeze if converted != 1}"
end

.convert_decimal(n) ⇒ Object

Converts a number to decimal byte units and outputs with the metric prefix For example,

LinuxStat::PrettifyBytes.convert_decimal(1000) # => “1.0 kilobyte” LinuxStat::PrettifyBytes.convert_decimal(1000 ** 3) # => “1.0 gigabyte” LinuxStat::PrettifyBytes.convert_decimal(1024 ** 3) # => “1.07 gigabytes”

.convert_short_binary(n) ⇒ Object

Converts a number to binary byte units For example,

LinuxStat::PrettifyBytes.convert_short_binary(1000) # => “1000 B” LinuxStat::PrettifyBytes.convert_short_binary(1000 ** 3) # => “953.67 MiB” LinuxStat::PrettifyBytes.convert_short_binary(1024 ** 3) # => “1.0 GiB”
