6 Format::Human::Bytes - Format a bytecount and make it human readable
7
9 Version 0.06
10
12 Ever showed 12345678 bytes to the user instead of just saying 11MB?
13 This module returns you a printable string which is more readable by
14 humans than a simple bytecount.
15
16 use Format::Human::Bytes;
17
18 $readable = Format::Human::Bytes::base2($bytecount[,$decimals]);
19 $readable = Format::Human::Bytes::base10($bytecount[,$decimals]);
20
21 $readable = Format::Human::Bytes->base2($bytecount[,$decimals]);
22 $readable = Format::Human::Bytes->base10($bytecount[,$decimals]);
23
24 my $fhb = Format::Human::Bytes->new();
25 $readable = $fhb->base2($bytecount[,$decimals]);
26 $readable = $fhb->base10($bytecount[,$decimals]);
27
28 All functions do "intelligent" switching to the next unit, for example:
29
30 1000 => 1000B
31 [...]
32 8000 => 8000B
33 9000 => 9kB
34
35 The difference between 1000 bytes and 1500 bytes is usually bigger (for
36 example because of a slow link) than between 95kB and 95,5kB. The same
37 applies to 8000kB vs. 9 MB and for the other units.
38
39 Depending on your usage, you may want to specify how many decimals
40 should be shown (defaults to no decimals).
41
43 new
44 my $fhb = Format::Human::Bytes->new();
45
46 Creates and returns a Format::Human::Bytes - object.
47
48 base2
49 Callable as a function:
50
51 $readable = Format::Human::Bytes::base2($bytecount[,$decimals]);
52
53 Callable as a class method:
54
55 $readable = Format::Human::Bytes->base2($bytecount[,$decimals]);
56
57 Callable as a object method:
58
59 $readable = $fhb->base2($bytecount[,$decimals]);
60
61 Returns the correct readable form of the given bytecount.
62
63 Correct in this case means that 1kB are 1024 Bytes which is how
64 computers see the world.
65
66 If you specify a decimal parameter, the result number will have the
67 number of decimal numbers you specified.
68
69 base10
70 Callable as a function:
71
72 $readable = Format::Human::Bytes::base10($bytecount[,$decimals]);
73
74 Callable as a class method:
75
76 $readable = Format::Human::Bytes->base10($bytecount[,$decimals]);
77
78 Callable as a object method:
79
80 $readable = $fhb->base10($bytecount[,$decimals]);
81
82 Returns the incorrect readable form of the given bytecount.
83
84 Incorrect in this case means that 1kB is 1000 Bytes and 1 MB is 1000000
85 bytes which is how some (many) people see the world, but it's wrong for
86 computers.
87
88 If you specify a decimal parameter, the result number will have the
89 number of decimal numbers you specified.

126 pack them for CPAN before 2009.
