Description

Hello,

Sorry if this has still been requested, I haven't found anything about this on the tracker. There is an inconsistent behavior between #to_f and Float() with strings. I don't know whether this is intended or not but if it is, there is at least something wrong in Kernel#Float's documentation:

Numeric types are converted directly, the rest are converted using arg.to_f.

>> "123.".to_f
=> 123.0
>> Float("123.")
ArgumentError: invalid value for Float(): "123."
from (pry):1:in `Float'

The issue has been originally reported here https://github.com/rails/rails/issues/11800.

Have a nice day.
