How to round calculated value in User System Data?

I met a problem to round he calculated N60 value to only two decimals in a designed report. The value was calculated from the following code (yellow color) in the user system data in Data Design. I tried format function as guided in the gINT but it doesn't work. Could anyone help me with this issue?

<<Let(Refusal Pen = <<User System Data.Refusal Penetration>>)>>_
<<ListBuildSepTrim(_
-,_
<<SAMPLE.Blows 1st>>,_
<<SAMPLE.Blows 2nd>>,_
<<SAMPLE.Blows 3rd>>,_
<<SAMPLE.Blows 4th>>_
)>>_
<<HasData(<<Get(Refusal Pen)>>,_
/<<Get(Refusal Pen)>>",_
<<DelimitData(_
<<cr>>(,_
<<Calc(<<SAMPLE.Blows 2nd>> + <<SAMPLE.Blows 3rd>>)>>,_
) [_
<<Calc((<<SAMPLE.Blows 2nd>> + <<SAMPLE.Blows 3rd>>) * <<POINT.Automatic Hammer Efficiency>> / 60)>>,_
)>>_
]_
)>>
