   * Returns one value if a condition you specify evaluates to TRUE and another value if it evaluates to FALSE.

   * Excel Function:

   *			For example, A10=100 is a logical expression; if the value in cell A10 is equal to 100,
   *			the expression evaluates to TRUE. Otherwise, the expression evaluates to FALSE.
   *			This argument can use any comparison calculation operator.
   *		ReturnIfTrue is the value that is returned if condition evaluates to TRUE.
   *			For example, if this argument is the text string "Within budget" and the condition argument evaluates to TRUE,
   *			then the IF function returns the text "Within budget"
   *			If condition is TRUE and ReturnIfTrue is blank, this argument returns 0 (zero). To display the word TRUE, use
   *			the logical value TRUE for this argument.
   *			ReturnIfTrue can be another formula.
   *		ReturnIfFalse is the value that is returned if condition evaluates to FALSE.
   *			For example, if this argument is the text string "Over budget" and the condition argument evaluates to FALSE,
   *			then the IF function returns the text "Over budget".
   *			If condition is FALSE and ReturnIfFalse is omitted, then the logical value FALSE is returned.
   *			If condition is FALSE and ReturnIfFalse is blank, then the value 0 (zero) is returned.
   *			ReturnIfFalse can be another formula.
