I think all these answers are missing the question   The problem was to  quot Round UP quot   not just  quot Round quot    It is my understanding that Round Up means that ANY fractional value about a whole digit rounds up to the next WHOLE digit   ie   48 0000000   48 but 25 00001   26   Is this not the definition of rounding up    or have my past 60 years in accounting been misplaced

You should use   inputvalue Math Round inputValue  2  MidpointRounding AwayFromZero    Math Round     Math Round rounds a double-precision floating-point value to a   specified number of fractional digits    MidpointRounding     Specifies how mathematical rounding methods should process a number   that is midway between two numbers    Basically the function above will take your inputvalue and round it to 2  or whichever number you specify  decimal places  With MidpointRounding AwayFromZero when a number is halfway between two others  it is rounded toward the nearest number that is away from zero  There is also another option you can use that rounds towards the nearest even number
