[issue27412] float('∞') returns 8.0
New submission from David Howlett:
float('inf') returns a float with a value of inf
float('∞') returns a float with a value of 8.0
I can't think of any justification for returning 8.0 other then ∞ looks like an
8 turned sideways. I believe float('∞') should return inf.

[issue27412] float('∞') returns 8.0
David Howlett added the comment:
I am using python 3.5 in a REPL in an IDE called Komodo running on Windows.
After reading your comments I wrote the following python file:
try:
x = float('∞')
except ValueError:
print('Value error was correctly thrown')
This throws a ValueError as you describe. I get the following behaviour in
powershell and cmd.exe:
>>> float('\u221e')
Traceback (most recent call last):
File "", line 1, in
ValueError: could not convert string to float: '\u221e'
In the Komodo REPL I see the following behaviour:
>>> '∞'
'8'
>>> '\u221e'
'\u221e'
I now believe the issue is with how Komodo reads in characters from its REPL.
In the course of testing I also found out that the REPL in Komodo suffers and
internal fault whenever it tries to print '∞' in a debug message.
Unless someone objects I will close this issue in the Python bug tracker and
open a new issue in the Komodo bug tracker.

David Howlett added the comment: I am sorry about misattributing this bug and wasting your time. I have opened two new bugs against Komodo: https://github.com/Komodo/KomodoEdit/issues/1760 https://github.com/Komodo/KomodoEdit/issues/1759 They are looking into it. -- ___ Python tracker <http://bugs.python.org/issue27412> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
