Delphi Round Function: How to Round Numbers in Delphi

The `Round` function in Delphi is used to round a floating-point number to the nearest whole number. It takes one parameter, which is the floating-point number to be rounded, and returns an integer value.\n\nHere is an example of how to use the `Round` function in Delphi:\n\ndelphi\nvar\n num1: Double;\n num2: Double;\n roundedNum: Integer;\n\nbegin\n num1 := 3.4;\n num2 := 5.8;\n\n roundedNum := Round(num1);\n ShowMessage('Rounded number 1: ' + IntToStr(roundedNum));\n\n roundedNum := Round(num2);\n ShowMessage('Rounded number 2: ' + IntToStr(roundedNum));\nend;\n\n\nIn this example, the `Round` function is used to round `num1` and `num2` to the nearest whole number. The resulting rounded numbers are then displayed using the `ShowMessage` function.
