This function converts NumberExpression into an integer string format; eg 23 becomes "23". FormatExpression (optional) determines the style of the returned string. Possible values of FormatExpression (the default is zero) are:

• 0 No trailing spaces, leading spaces or zeros, or comma separators are included
• 1 Leading zeros are included
• 2 Trailing spaces are included
• 3 Leading spaces are included
• +4 Comma separators are included; add this value to one of the above.

LengthExpression is optional, but you must specify it if you need padding with spaces or zeros, and the value must be large enough to fit the number including any comma separators.

This example converts 1234567 to the string "0001,234,567".
