Issue description

This was reported on Weblate against the 3.x docs, but it's likely the same in master (didn't test but the code and docs are the same).

The wrapf documentation gives this example:

# Infinite loop between 5.0 and 9.9
value = wrapf(value + 0.1, 5.0, 10.0)

But if you run this code with e.g.:

var value = 0

func _process(_delta):
    value = wrapf(value + 0.1, 5.0, 10.0)
    print(value)

It prints:

5.1
5.2
5.3
5.4
5.5
5.6
5.7
5.8
5.9
6
6.1
6.2
6.3
6.4
6.5
6.6
6.7
6.8
6.9
7
7.1
7.2
7.3
7.4
7.5
7.6
7.7
7.8
7.9
8
8.1
8.2
8.3
8.4
8.5
8.6
8.7
8.8
8.9
9
9.1
9.2
9.3
9.4
9.5
9.6
9.7
9.8
9.9
10
5.1
5.2
5.3

So it seems to wrap between 5.1 and 10.0.

Either the docs or the implementation are wrong.

(Confirmed in 4.0) I think it's a bug in the implementation ^^.
