Summary: Ruby fails float 80 test in stable tarball (2 May
2006) when compiled with Mingw

Initial Comment:
Hi all

After compiling Ruby stable with Mingw I get

$ ./ruby -v
ruby 1.8.4 (2006-05-01) [i386-mingw32]

the 'make check' command produces:

$ make check
not ok float 80 -- ./sample/test.rb:1209
test failed
make: *** [test] Error 1

I changed the sample/test.rb code to have more info on the
issue:

........ start at line 1204 in sample/test.rb .....

#s = "3.7517675036461267e+17"
#test_ok(s == sprintf("%.16e", s.to_f))

# NEXT 2 LINES ADDED BY ME #######
print ">>>",f,"\n"
print
">>>",sprintf("%.16e",
f).to_f,"\n"

f = 3.7517675036461267e+17
test_ok(f == sprintf("%.16e", f).to_f)

.............................................

The result:

$ ./ruby sample/test.rb 
assignment
ok 1
ok 2
ok 3
.......................
ok 77
ok 78
ok 79
>>>3.75176750364613e+017
>>>3.75176750364613e+017
not ok float 80 -- sample/test.rb:1209
bignum
ok 1
...........................

Apparently the two strings are equal. Has this something
to do with the '==' operator?

Thanks

I think I fixed it.  Try it again with the latest stable
snapshot,
please.
