FormatPercent(expression[, fractionaldigits[,leadingdigit[, parensfornegative[, groupdigits]]]])


FormatCurrency, FormatNumber, and FormatPercent return a string obtained by formatting the given expression as a currency, number, or percent. The required parameter, expression, is any valid expression of the given type.

The optional parameter, fractionaldigits, is a numeric expression representing the number of digits to print after the decimal. The default is -1 which uses the system settings.

The optional parameters, leadingdigit, parensfornegative, and groupdigits, are tristate values. See table below.

leadingdigit specifies whether a leading zero is printed for numbers with only fractional parts.

parensfornegative specifies if negative values are to be printed with enclosing parentheses.

groupdigits specifies if numbers are to be printed in groups using the systems group delimiter.
