Bug #9810: Numeric#step behavior with mixed Float, String arguments inconsistent with documentation
https://bugs.ruby-lang.org/issues/9810#change-57687
* Author: Brian Shirai

----------------------------------------
The `Numeric#step` documentation states:
"If any of the arguments are floating point numbers, all are converted to floats..."
https://github.com/ruby/ruby/blob/trunk/numeric.c#L1921
Is the following code intended to be described by that documentation?
```ruby
1.1.step(5.1, "1") {}
```
Previously (eg 2.0.0) resulted in a `TypeError`:
```
$ ruby -v -e 'p 1.1.step(5.1, "1") {}'
ruby 2.0.0p247 (2013-06-27) [x86_64-darwin13.0.1]
-e:1:in `step': no implicit conversion to float from string (TypeError)
from -e:1:in `<main>'
```
In 2.1.1, at least, an `ArgumentError` is raised:
```
$ ruby -v -e 'p 1.1.step(5.1, "1") {}'
ruby 2.1.1p76 (2014-02-24 revision 45161) [x86_64-darwin13.0]
-e:1:in `>': comparison of String with 0 failed (ArgumentError)
from -e:1:in `step'
from -e:1:in `<main>'
```
What's the intended behavior?
