  Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

Returns a sortable textual representation of a numeric value.
To text-sort numbers, you will have to pad them with zeros.
To be able to cope with negative values, subfunction FlipDigits()
is used, to convert these into text, that when padded with nines
will turn the smallest value into the largest one.
Finally, positive values will be preceded by a "9", while negative
values will be prefixed wit a "0".
This will result in textvalues that will sort correctly, for instance
in a portal-sort solution.

Syntax: NumToSortableText ( value ; decimals )
Return type: Text

Uses function FlipDigits() defined earlier.
