x.abs seems to me a convenience method.

If you're using irb in math mode or something like this, this might
make your functions look prettier:

>> module Math
>>   def abs(x)
>>     x.send(:abs)
>>   end
>> end
=> nil
>> include Math
=> Object
>> abs(10)
=> 10
>> abs(-10)
=> 10
>> abs(-10.2114125)
=> 10.2114125
