Method: LinuxStat::PrettifyBytes.convert_binary

Defined in:
lib/linux_stat/prettify_bytes.rb

.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”
