Parámetros:

expression: Required. The numeric expression to be formatted.

numDigitsAfterDecimal: Optional. A numeric value specifying the number of digits that should be displayed after the decimal. If omitted, it defaults to the value -1, meaning that the default settings for user interface locale should be used.

includeLeadingDigit: Optional. A vbTriState enumeration value, specifying whether a leading zero should be displayed for fractional values.

useParensForNegativeNumbers: Optional. A vbTriState enumeration value specifying whether negative numbers should be encased in parenthesis.

groupDigits: Optional. A vbTriState enumeration value specifying the number should be grouped (into thousands, etc.), using the group delimiter that is specified on the system's regional settings.
