number_to_human_size

Formats the bytes in number into a more understandable representation (e.g., giving it 1500 yields 1.5 KB). This method is useful for reporting file sizes to users. You can customize the format in the options hash.

See number_to_human if you want to pretty-print a generic number.

Options

• :locale - Sets the locale to be used for formatting (defaults to current locale).

• :precision - Sets the precision of the number (defaults to 3).

• :significant - If true, precision will be the # of significant_digits. If false, the # of fractional digits (defaults to true)

• :separator - Sets the separator between the fractional and integer digits (defaults to â.â).

• :delimiter - Sets the thousands delimiter (defaults to ââ).

• :strip_insignificant_zeros - If true removes insignificant zeros after the decimal separator (defaults to true)

• :prefix - If :si formats the number using the SI prefix (defaults to :binary)

Examples

number_to_human_size(123)                                    # => 123 Bytes
number_to_human_size(1234)                                   # => 1.21 KB
number_to_human_size(12345)                                  # => 12.1 KB
number_to_human_size(1234567)                                # => 1.18 MB
number_to_human_size(1234567890)                             # => 1.15 GB
number_to_human_size(1234567890123)                          # => 1.12 TB
number_to_human_size(1234567, precision: 2)                  # => 1.2 MB
number_to_human_size(483989, precision: 2)                   # => 470 KB
number_to_human_size(1234567, precision: 2, separator: ',')  # => 1,2 MB

Non-significant zeros after the fractional separator are stripped out by default (set :strip_insignificant_zeros to false to change that):

number_to_human_size(1234567890123, precision: 5) # => "1.1229 TB"
number_to_human_size(524288000, precision: 5)     # => "500 MB"
