NAME¶

Format::Human::Bytes - Format a bytecount and make it human readable

VERSION¶

Version 0.06

SYNOPSIS¶

Ever showed 12345678 bytes to the user instead of just saying 11MB? This module returns you a printable string which is more readable by humans than a simple bytecount.

    use Format::Human::Bytes;
    $readable = Format::Human::Bytes::base2($bytecount[,$decimals]);
    $readable = Format::Human::Bytes::base10($bytecount[,$decimals]);
    $readable = Format::Human::Bytes->base2($bytecount[,$decimals]);
    $readable = Format::Human::Bytes->base10($bytecount[,$decimals]);
    my $fhb = Format::Human::Bytes->new();
    $readable = $fhb->base2($bytecount[,$decimals]);
    $readable = $fhb->base10($bytecount[,$decimals]);

All functions do "intelligent" switching to the next unit, for example:

    1000 => 1000B
    [...]
    8000 => 8000B
    9000 => 9kB

The difference between 1000 bytes and 1500 bytes is usually bigger (for example because of a slow link) than between 95kB and 95,5kB. The same applies to 8000kB vs. 9 MB and for the other units. Depending on your usage, you may want to specify how many decimals should be shown (defaults to no decimals).

FUNCTIONS / METHODS¶

new¶

    my $fhb = Format::Human::Bytes->new();

Creates and returns a Format::Human::Bytes - object.

base2¶

Callable as a function:

    $readable = Format::Human::Bytes::base2($bytecount[,$decimals]);

Callable as a class method:

    $readable = Format::Human::Bytes->base2($bytecount[,$decimals]);

Callable as a object method:

    $readable = $fhb->base2($bytecount[,$decimals]);

Returns the correct readable form of the given bytecount. Correct in this case means that 1kB are 1024 Bytes which is how computers see the world. If you specify a decimal parameter, the result number will have the number of decimal numbers you specified.

base10¶

Callable as a function:

    $readable = Format::Human::Bytes::base10($bytecount[,$decimals]);

Callable as a class method:

    $readable = Format::Human::Bytes->base10($bytecount[,$decimals]);

Callable as a object method:

    $readable = $fhb->base10($bytecount[,$decimals]);

Returns the incorrect readable form of the given bytecount. Incorrect in this case means that 1kB is 1000 Bytes and 1 MB is 1000000 bytes which is how some (many) people see the world, but it's wrong for computers. If you specify a decimal parameter, the result number will have the number of decimal numbers you specified.
