Something like this:

var decimalValidation = worksheet.DataValidations.AddDecimalValidation("A:A");
decimalValidation.ShowErrorMessage = true;
deciamlValidation.ErrorStyle = ExcelDataValidationWarningStyle.stop;
decimalValidation.ErrorTitle = "The value you entered is not valid";
decimalValidation.Error = "This cell must be a valid positive number.";
decimalValidation.Operator = ExcelDataValidationOperator.greaterThanOrEqual;
decimalValidation.Formula.Value = 0D;
