Code Review (External): NumericalFixes


#1

A number of fixes to pass most of the relevant rubyspecs.

            BignumOps.cs: Leftshift and Rightshift fixes

            FixnumOps.cs: Leftshift, Rightshift, Bitwise_Xor,

Bitwise_And and Bitwise_Or fixes

            FloatOps.cs: Constant and IsNegativeZero modification. 

Also
partial fix to ToS

            Integer.cs: DownTo and UpTo fixes

            Numeric.cs: Remainder and Step fixes.

(There are now only 2 failures in Numeric, 1 in Float and a number in
Bignum.)

If you are running against the RubySpec’s version of RubySpecs (as
opposed to the IronRuby repo) you may want to sync and test again. I
pushed some changes last night that make some of the float comparison do
numerical comparisons instead of string comparisons.

Thanks Jim. I pulled the latest rubyspecs and there are no unexpected
failures.

Still waiting for someone to review my code…

Pushed the bug fixes to SVN r160. Someone on MS side needs to look at
ironruby-tags and make sure it is up to date.

out r159 in a few minutes, so you’ll need to update and regenerate the

#7

You changed this line:

        StringFormatter sf = new StringFormatter(scope, "%.15g", new 

object[] { self });

To:

        StringFormatter sf = new StringFormatter(scope, "%.14g", new 

object[] { self });

Why the reduced # of digits? This is causing one of the specs to fail:

Math.sqrt returns the square root of the argument FAILED
Expected “123456789.12346”
to equal “123456789.123457”

#8

I have submitted two bugs regarding this: 22384
<http://rubyforge.org/tracker/index.php?func=detail&aid=22384&group_id=4359&
atid=16798> and 22385
<http://rubyforge.org/tracker/index.php?func=detail&aid=22385&group_id=4359&
atid=16798> . I think for now you get less weirdness if you revert my
change below back to

        StringFormatter sf = new StringFormatter(scope, "%.15g", new

object[] { self });

But this is still not right. The problem is that the trailing zero is
being
added in after the formatting but that a) it should be counted as a
significant digit and b) it is not being picked up when there is an
exponent
displayed. I think that the StringFormatter needs to be fiddled with to
sort this out but I am wary of entering into this rather complex beast
in
case I break other stuff.

Pete

#9

OK, I mean to raise a bug about this one. There is some funniness
inside
MRI’s string formatting of floating point numbers. Feel free to change
it
back but then one of the Float specs fails.

I think the relevant one is something like:

10000000000000.0.to_s.should == “100000000000000.0”

100000000000000.0.to_s.should == “1.0E+15”

But IronRuby produces “1.0E+14” and “1.0E+15” or something like that. I
think it has to do with whether you count the trailing zero as a
significant
digit.
