Guidelines

If you a loop-control variable of any type other than integer there is a risk that rounding errors will accumulate as it is incremented repeatedly. In addition, if the expressions for the start, limit, and step values are not of integer type the number of iterations may not be what you expect because the formula uses the INT function (not NINT). None of these problems can occur if integer quantities are used throughout the DO statement.
