That's not quite the equivalent of float(), I would say: this one
apparently is locale-aware, so it is more the equivalent of locale.atof.
Right. It is *the* standard way of getting a float from a string though,
whereas in Python we have two depending on whether or not you want to be
locale aware. The standard way in C# is locale aware. To be non-locale
aware you pass in a specific culture or number format.
The next question then is if it supports indo-arabic digits in any
locale (or more specifically in an arabic locale).
I don't think so actually. The float parse formatting rules are defined
like this:
[ws][$][sign][integral-digits[,]]integral-digits[.[fractional-digits]][E[sign]exponential-digits][ws]
(From http://msdn.microsoft.com/en-us/library/7yd1h1be.aspx )
integral-digits, fractional-digits and exponential-digits are all
defined as "A series of digits ranging from 0 to 9". Arguably this is
not be conclusive. In fact the NumberFormatInfo class seems to hint that
it may be otherwise:
http://msdn.microsoft.com/en-us/library/system.globalization.numberformatinfo.aspx
See DigitSubstitution on that page. I would have to try it to be sure
and I don't have a Windows VM in convenient reach right now.
All the best,
Michael
