Hello
I was wondering if there is a bug in GHC 6.10.1 regarding number precision.
As an example, in GHCi with:
> 3.0 * 0.2
I get:
0.6001
Although:
> 2.0 * 0.2
0.4
I have GHC 6.10.1 on Mac OS X 10.5.
Is this a known bug or should I report it?
Best regards
Zé Pedro
Hi,
Floating point numbers are just inaccurate, so the results you see aren't too
surprisingly.
Interestingly enough, using Hugs, I get the right answer in both cases - so its
possible it's a bug, but unlikely.
If you do want exact floating point manipulation then use rational numbers
instead

computers store floating-point numbers in binary form, and it's
imposiible to represent 3/5 in binary form exactly for the same
reasons as impossibility to represent 1/3 exactly in decimal form

Is there a tentative release date for 6.10.2?

I can setup an login for a GHC developer on my Zen instance, if that

This is a straight forward ld.so path problem, by the sounds of it.
Are you sure you're setting ld environment search paths correctly?

Is your LD_LIBRARY_PATH environment variable exported, and set to
include the path to the lib dir that libedit lives in?
e.g.
$ echo $LD_LIBRARY_PATH
/home/dons/lib
Allows the system linker to find things in my home dir.

It sounds like your tree is mucked up somehow.
The process should be quite simple:
* download the ghc binary release for your platform (e.g. x86_64/linux)
* set LD_LIBRARY_PATH to include the directory of any non-standard dynamic
libraries.
And you are done.
Can you try this?
