NAME

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

VERSION

Version 0.05

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.

The functions are in use since late 2003 or early 2004 but I didn't pack them for CPAN before 2009.
