Formatting Numeric Values in Script

Howdy,

I'm a TGB noob.
Can someone enlighten as to how to format numeric values in script.

For example:
A) rounding 12.3456 to 12.35 (with variable decimal precision),
B) truncating 12.3456 to 12.3 (with variable decimal precision),
etc.

I had assumed there would be a TorqueScript version of printf(), and there is, but it appears to only be available when formatting data for display on the console.

Am I just wrong? Missing the obvious? Fruitlessly optimistic?

Help Mr. Wizard!
