Prevent floating number precision issue

Some test runs would cause runid to end up with a slightly differing values
which caused the tests to fail.

An example of failing test is when $runid was observed to be 153.425536363056,
but in the database it is stored as '153.42553636305601'. This caused the
Attribute to not be found causing some of the tests to fail.

I see no need for a long fraction to be used, so truncate it.
