query prepare with sql math

[GuL]

I have tested your code and it returns "2".

Something strange is happening, because when I change

query.prepare("select :a / :b");

query.prepare("select :a / :b");

To copy to clipboard, switch view to plain text mode 

to

query.prepare("select :a + :b");

query.prepare("select :a + :b");

To copy to clipboard, switch view to plain text mode 

or

query.prepare("select :a - :b");

query.prepare("select :a - :b");

To copy to clipboard, switch view to plain text mode 

or

query.prepare("select :a * :b");

query.prepare("select :a * :b");

To copy to clipboard, switch view to plain text mode 

it returns me the right result.
Do you see anything wrong with my code?
