Clarify "precision" in currency format functions 

The documentation of the FormatAccounting and FormatCurrency
functions could be clearer in terms of how the precision param
works. This commit makes it more explicit that adding a precision
of < 2 will not format the return values to include fewer decimals.

Resolves #8858
