Store binary data into SQL Database

In my tests, with built-ins, the 4 * atan(1) version is fastest on GCC 4.2, because it auto-folds the atan(1) into a constant. I've included it as a baseline to compare against the other versions. The inline assembly version is, in theory, the fastest option, though clearly not portable. The program below tests the various ways I know of. More specifically, I'm using ways that don't involve using #define constants like M_PI, or hard-coding the number in. I'm looking for the fastest way to obtain the value of π, as a personal challenge.

Id INT(4) NOT NULL AUTO_INCREMENT PRIMARY KEY, How can I get the result set of a LINQ query into a DataSet or DataTable? Alternatively, is the LINQ query serializable so that I can expose it as an ASMX web service?įilling a DataSet or DataTable from a LINQ query result set copy LINQ query resultset into a DataTable -this does not work !

Identifying the constant as 5000.0 (or as 5000d) is sufficient: Percentage width child element in absolutely positioned parent on Internet Explorer 7Īn explicit cast to double like this isn't necessary:ĭouble trans = (double) trackBar1.Value / 5000.0 Is there an area of the CSS specification that covers this? Is there an easy fix for this besides the pixel-based width on the If the parent is relatively positioned, the percentage width on the child works. When I use a percentage-based width on the child div, it collapses to '0' width on Internet Explorer 7, but not on Firefox or Safari.

I have an absolutely positioned div containing several children, one of which is a relatively positioned div. This code worked fine in a past VB.NET project. I tried using trans and double but then the control doesn't work. When I build the application, it gives the following error:Ĭannot implicitly convert type 'decimal' to 'double'. I want to use a track-bar to change a form's opacity.
