Converting date to hour

The formula listed below is giving me an error. Should I start the formula with an "IF"?

=([Derivatives Processed per Hour by Workflow].[Completion Full Date])-([Derivatives Processed per Hour by Workflow].[Digitization Completion Date]*24)

    You can calculate the difference between dates in seconds and convert it to hours.

    Formula for seconds calculation

    =DaysBetween([Completion Full Date] ;[Digitization Completion Date]) * 86400



    ToNumber(FormatDate([Digitization Completion Date] ;"HH")) * 3600 +

    ToNumber(Left(FormatDate([Digitization Completion Date] ;"mm:ss") ;2)) * 60 +

    ToNumber(FormatDate([Digitization Completion Date] ;"ss"))




    ToNumber(FormatDate([Completion Full Date] ;"HH")) * 3600 +

    ToNumber(Left(FormatDate([Completion Full Date];"mm:ss") ;2)) * 60 +

    ToNumber(FormatDate([Completion Full Date] ;"ss"))

    Then convert the value to hours using the formula
