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.
