Formatting Numbers Part 3 : Percentages

The function you need to format percentages is FormatPercent. It is very easy to use and has been outlined and explained below:

FormatPercent(NumToBeFormatted[, NumOfDigitsAfterDecimal, IncludeLeadingDigit, UseParensForNegativeNumbers])
- returns a formatted percentage from the number specified with the appropriate number of digits specified after the decimal and a trailing '%' sign.
- the first parameter is the only one that is required, although I recommend that you use at least include the second parameter.
- the last two parentheses are tristate values which means you need to specify a -1 for true, 0 for false, or -2 to use the computers regional settings.
- the IncludeLeadingDigit parameter is used to specify whether or not you want a leading zero to be displayed when the number is a fractional value.
- the UseParensForNegativeNumbers parameter is pretty self explanatory, if set to true it will put parentheses around negative numbers.

Example:

var1 = 5.4333
var2 = .823
Response.Write("var1 formatted = " & FormatPercent(var1, 2, -1, -1) & "<br>")
Response.Write("var2 formatted = " & FormatPercent(var2, 1, -1, -1))

Result:
var1 formatted = 543.33%
var2 formatted = 82.3%
