Proposing adding a ceiling alias to the ceil instance method for Numeric, Float, Integer.

Although ceil is familiar as it's an extremely common method name in other languages, ceiling is more readable. Several other methods exist in the standard library with aliased long and short forms. A few examples:

Numeric:
[:imaginary, :imag]
[:rectangular, :rect]
[:to_i, :to_int]
[:conjugate, :conj]

String:
[:to_str, :to_s]

Usage:

> 2.71.ceil
 => 3
> 2.71.ceiling
 => 3

> Fixnum.instance_methods.grep /ceil/
 => [:ceil, :ceiling]

I do not have any particular pro or con opinion here; personally I would continue to use .ceil but if other people use .ceiling
by default, it is up to them, not me. There is more than one way to do something.

I should, however had, point out that you equated String to_str with to_s and they are not the same.

Having both ceil (backed by UNIX tradition) and ceiling (better for English natives? dunno) only introduces confusion. Is there any other buying point for ceiling?
