Description Wyatt Childers 2014-10-20 00:07:27 UTC 
Whenever you try to use a floating point integer as the first number of a calculation, the calculator runner is not triggered. 

If the operation is multiplication the following works:
"5*5"
"4.3*6."
"4.3*6="
"4.3*6.0="
"4*6.0="
But the following does not:
"4.3*6"
"4.4*6.0"
"4*6.0"

If the operation is division the following works:
"5/5"
"5/5="
But the following does not:
"5.5/5"
"5.5/5="
"5.5/5.5"
"5.5/5.5="
"5/5.5"
"5/5.5="
* Division is the most severly broken, as even when specifying the equals sign the calculator is not triggered.

If the operation is addition the following works:
"5+4"
"5+5="
"5.5+4="
"4+5.5="
But the following does not:
"5.5+4"
"4+5.5"

If the operation is subtraction the following works:
"5-4"
"5-5="
"5.5-4="
"4-5.5="
But the following does not:
"5.5-4"
"4-5.5"

Reproducible: Always

Steps to Reproduce:
Enter one of the describe combinations that do not work into Krunner with the calculator enabled.

Actual Results:  
For the input 5.5+4, Locations Go to http://0.5.0.4 will be triggered for 5.5+4.

Expected Results:  
For the input 5.5+4, or some other valid mathematic expression, the calculator runner will be triggered resulting in -- for this case -- 9.5.

I'm using Manjaro, so the packages aren't 100% Arch packages, but there should be virtually no difference.

Confirmed. This seems to be problem with the KRunner Framework. Here is the offending commit -

    add some heuristics to recognize urls

    QUrl::fromUserInput is way more stupid than KProtocolInfo
    It will produce an http url from pretty much any string,
    so ignore http urls of words without a dot (ie kde.org will
    become http://kde.org but  kde will not be considered an url)

Pushed by vhanda into branch 'master'.

Do not detect anything with a '.' as a NetworkLocation

One can also uses a decimal point in a calculator.
