HumanBytes

Convert bytesizes into a human-readable format

Either uses decimal byte prefixes or prefixes based on powers of 2 (Ki, Mi, etc.). The functionality is exposed as a:

module function named HumanBytes.human_bytes
includable submodule HumanBytes::MethodVersion for numeric types
simple executable named human_bytes

Arbitrary precision arithmetic is used so that even astronomical bytesizes are handled correctly.

Module function

include HumanBytes
Humanbytes.human_bytes(1024) #=> '1.00 KiB'
human_bytes(1050, places: 10) #=> '1.0253906250 KiB'
human_bytes(1050, places: 3, i: false) #=> '1.050 KB'

Includable submodule

Numeric.include(HumanBytes::MethodVersion)
1024.human_bytes #=> '1.00 KiB'
1050.human_bytes(places: 10) #=> '1.0253906250 KiB'
1050.human_bytes(places: 3, i: false) #=> '1.050 KB'

Executable

$ echo 1024 | human_bytes -d #=> 1.00 KiB
$ echo 352853503285093280958325083205832| human_bytes #=> 291873576.99 YiB
