Hi,
(1) I have met several cases where epsilon is added to a non-negative variable to guarantee nonzero value. So I wonder why not add the minimum value that the data type can represent instead of epsilon? What are the difference problems that these two...

In the case of double precision, the difference between the maximum and the next, there is no strict answer, it depends....
It depends on the precision of the floating point number of course.
Is actually 1e-16 while the second is approx 1e+11.

I'm using long double in a C program to compute 2D images of the Mandelbrot Set but wish to have further precision to zoom deeper.
Are there any performance gains to be had from an arbitrary precision maths library that can restrict the amount of precision...

Ever since Precision X was released many have been requesting a smaller skin (myself included). The interface became much larger than the previous iterations of Precision we'd grown accustomed to. For those who had used MSI AfterBurner the jump in size...

You will have to modify your decimal(precision, scale) replacing the precision and scale with your desired values.
In the properties at the bottom there is a precision property
None that I'm aware of.

Precision loss is one thing, but precision gain???
I have a text file w/ the following coordinates:
41.88694340165634 -87.60841369628906
When I paste this into SQL Server Mgmt Studio table view, it results in this:

It's not adding precision to decimal, it only LOOKS like it gained precision..
Remember that floats are all approximate anyway.

From the article:
from math import log as _flog def log(x): if x < 0: return, the python quick start tutorial discusses the arbitrary precision: http://docs.python.org/lib/decimal be "%d\n".

Hello
I have two questions
1- what is the "11pt average precision metric"?
2- and how to use it in information retrieval?
Thanks

As far as I can see 11 point average precision is an evaluation of how well to Information Retrieval
and there is a reference to 11-point interpolated average precision use, you have precision and recall.
Defined terms.

What's the best way to trim a DateTime object to a specific precision? For instance, if I have a DateTime with a value of '2008-09-29 09:41:43' and but I only want it's precision to be to the minute, is there are a better way to do it than this?

I am trying to populate a string with the double value using a sprintf like this sprintf(S, "%f", val); But the precision is being cut of to 6 decimal places. I need about 10 decimal places for the precision.
Kindly tell me how that can be achieved.

%8.2 means 8.

Width should include the decimal point.
