I notice in some Velocity reports I'm working with that $fn contains some built in functions for Velocity. I can't seem to find a list of these. For example, `$fn.formatNumber($fn.duration($time),'##0.0')

My google-fu has failed me on this one. Anyone have link to the docs on this?

Those are not built in. It is some utility class that either is getting added to every context somewhere or is registered in velocity-tools.xml as a custom tool.
