Before this commit, when the value is null in the pivot view on a float
field, we format the value before displaying it. The problem is the
formatFloat method does not check if the value is null and used the
`toFixed` method to fixed the number of digits to display for the value.
This commit uses the value if it is not value otherwise use 0 to fixed
the number of digits. That is, when the value is null, the formatter
will return "0.00" (if the number of digits expected is 2) instead of
raise an error.
Steps to reproduce:
==================
1) Go to the helpdesk App > Reporting > Tickets Analysis.
2) Go to pivot view of this report.
3) Add the measure called "Rating (/5)"
Expected behaviour:
==================
Show the pivot with empty cells or 0.00 if the average of this measure
has no values.
Actual behaviour:
================
Traceback shown because it cannot read 'toFixed' property of null.
