NUMBERVALUE (was: [office-formula] NUMBERVALUE and VALUE)

Hi,

Any opinions on NUMBERVALUE regarding the points I mentioned:

- Introduction of a third parameter for group AKA thousand separator.
  Strictly spoken, for a group separator we'd also need a fourth
  parameter to define the grouping, defaulted to "3" (for Western
  1,000,000), which could be set to "23" (for Indic 1,00,00,000).

- Do not define it as yet another "try to parse as much as possible"
  function, hence no fallback to VALUE with exchanged separators. Parse
  only numbers, do not try to attempt parsing dates/times/currencies/...
