adding convience aliasing to duplicate old precision behavior and new scale

Since scale is what we are looking for and that is precision=n notation='fixed'

this can have parody during merge and we can implement scale from apangea at our leisure

The old precision mechanism is now handled under significantDigits.
Later we can eliminate 'precision' as an option so we don't get cornfused
