The following example uses the FormatNumber function to format a number to have four decimal places:

Function FormatNumberDemo
  Dim MyAngle, MySecant, MyNumber
  MyAngle = 1.3                \' Define angle in radians.
  MySecant = 1 / Cos(MyAngle)  \' Calculate secant.
  FormatNumberDemo = FormatNumber(MySecant,4) \' Format MySecant to four decimal places.
End Function
