You're still using automatic translation software: it isn't helping you.
Qu'est que ça veut dire = "what does that/this mean?" (or near enough)
You need to read the docs.
perldoc POSIX
ceil This is identical to the C function "ceil()", returning the
smallest integer value greater than or equal to the given numerical
argument.
floor This is identical to the C function "floor()", returning the
largest integer value less than or equal to the numerical
argument.

use (perldoc -f use) the POSIX (perldoc POSIX) module and import the
ceil() and floor() functions, so that you can use them in your code.
leia:~ [15:24:17]$ perl -MPOSIX=floor,ceil -le 'print for map {$_,
floor($_), ceil($_)} 1.5, 1.999, 2.001'
1.5
