On Epsilon, MachineEpsilon, and relative differences – via: I was wondering, that what is the closest value to the Zero floating point can have – G+
Posted by jpluimers on 2015/10/07
A long time ago, there was an interesting discussion here: I was wondering, that what is the closest value to the Zero floating point can have.
Recently I needed to do some calculations on series where getting close to zero could become a problem.
- Math seems to have an Epsilon of 1E-12.
- Sytem.Types has Epsilon of 1E-30 and Epsilon2 of 1E-40.
- XE4+ FMX has IsEssentiallyZero and IsNotEssentiallyZero for Single values.
In practice it depends a lot on what you are doing. Sometimes absolute Epsilons are best, but at other times relative difference is much more applicable.
Then there is also a Machine Epsilon: a way to derive an Epsilon from a data type that works in all languages and platforms.

NUnit XSD for verification and XML to HTML conversion
Posted by jpluimers on 2015/10/01
Of course NUnit will emit NUnit compatible XML, but other tools do too.
To verify if such XML is indeed compliant to the NUnit standard, there is an XML Schema for it which – at the time of writing – the latest version was here:
Many CI tools map the resulting XML into some form of output. To get HTML output, XSLT is a logical choice, but there are other means too. Here are a few links to get started converting the output:
- formatting – How to convert NUnit output into an HTML report – Stack Overflow (thanks Grhm).
- JatechUK/NUnit-HTML-Report-Generator (thanks Luke for sharing this).

Visual Studio: Zoom Out when ReSharper has captured Ctrl+Shift+,
Posted by jpluimers on 2015/09/30
ReSharper has a whole set of nice keyboard shortcuts, which includes Ctrl + Shift + , for View Recent Edits.
This overwrites the Zoom Out half of the default Visual Studio zoom keyboard shortcuts (thanks Carlos Muñoz):
Ctrl + Shift + . to zoom in and Ctrl + Shift + , to zoom out.
They don’t keep an alternative for Zoom Out, and unlike most tools I know that allow for zooming, there is no keyboard accessible menu entry for Zoom Out in Visual Studio.
So you have to use your mouse to go in the lower left of your editor window in order to Zoom Out (thanks ashteele for putting that in an SO question):
Or you can reconfigure the old shortcut (thanks Aaron Ransley):
through
Tools->Options->Environment->Keyboardand map “View.ZoomIn” and “View.ZoomOut“

Unless you write an installer with the right manifest, don’t include Installer, Update, Upgrade, Setup, … in your EXE name
Posted by jpluimers on 2015/09/28
I’ve seen this question coming up a few times, and bumped into this at a client recently: the UAC dialog coming up when debugging a 32-bit executable.
This is caused (more details below) by Installer Detection Technology introduced in Windows Vista (with UAC) and tightened in more modern Windows versions.
The solution is to either:
- not include Installer, Patch, Update, Upgrade, Setup, … in your EXE name
- provide a correct manifest to your EXE (getting this right can be hard)
- don’t use x86 as platform target
For software you don’t have source code for, you can alter the manifest with a requestedExecutionLevel element: Fixing the way Vista Auto-detects Installers – Ben’s Writing.

A while ago Allen Bauer commented on the working theory of Nullable in Delphi
Posted by jpluimers on 2015/09/25
I missed this last May, but revisiting some old G+ posts I saw Allen Bauer commenting:
Current working theory of Nullable<T>.
Nullable<T> = record
...
property Value: T read FValue; default;
...
end;Using the default directive to “hoist” the operators of “T”. Currently the default directive only works for array properties by “hoisting” the ‘[]’ operator. Marking a non-array property with default will make the containing type behave as that type.
This, coupled with some intrinsic compiler knowledge of the Nullable<T> type will make Nullable<T> work without any addition of keywords or other standard functions or procedures.
Using the “default” directive on a non-array property will work for any type, except for having the null-propagation semantics.
When considering language features, I try and not only make it work for the intended purpose, but also broaden reach of any supporting feature. In the above scenario, even user-defined operators on “T” will be properly hoisted and used.
So hopefully, one day there will me more than Nullable<T> in Spring.pas which has been around for quite a while now..
