[ruby-core:88042] [Ruby trunk Bug#14926] Different results between Enumerable#sum and #reduce when Float::INFINITY present

Issue #14926 has been updated by ahorek (Pavel Rosický).


Ask two people to imagine an infinite number, they won't be equal. The behaviour is correct. Infinity != Infinity

----------------------------------------
Bug #14926: Different results between Enumerable#sum and #reduce when Float::INFINITY present
https://bugs.ruby-lang.org/issues/14926#change-73059

* Author: swistak35 (Rafał Łasocha)
* Status: Open
* Priority: Normal
* Assignee: 
* Target version: 
* ruby -v: ruby 2.5.1p57 (2018-03-29 revision 63029) [x86_64-linux]
* Backport: 2.3: UNKNOWN, 2.4: UNKNOWN, 2.5: UNKNOWN
----------------------------------------
When `Float::INFINITY` is present in array, `Enumerable#sum` and `Enumerable#reduce(0, &:+)` are giving different results.

```
puts [Float::INFINITY].sum
puts [Float::INFINITY].reduce(0, &:+)
```

results in

```
NaN
Infinity
```

And I would expect both of them to be `Infinity` (meaning: `#sum` is working incorrectly).

Checked on `ruby 2.5.1p57` and `ruby 2.4.3p205`, both have the same bug.
