Converts numbers into words
API Declarations
' **************************************************
' Description : Module that will transform numbers into
' words
' Author : Ulysses R. Gotera
' Email : [email protected]
' Country : Philippines
' Date Created : Sunday, February 19, 2006
' Date Modified: <>
' Note : This program assumes that the number you are
' going to input is in this format 999999999999.99
' (up to 999 billion)
'
' This program will not work if a dot is used instead
' of a comma in seperating ones, hundreds, thousands, and millions.
' Some coutries use a dot instead of a comma.
'
' Sample Usage:
' strVariable = udf_strNum2Words(100.50,"Pesos ", "Centevo(s)")
' Debug.Print strVariable
'
' This will result in:
' One Hundred Pesos and Fifty Centevo(s)
'
'
' strVariable = udf_strNum2Words(8788.69,"Dollars ", "Cents")
'
' This will result in:
' Eight Thousand Seven Hundred Eighty Eight Dollars and Sixty Nine Cents
'
'
' strVariable = udf_strNum2Words(88)
'
' This will result in:
' Eighty Eight
