```d
import std.math : isNaN;

float lnumStockPricePreceding;

foreach (float lnumStockPrice; ludtStockPriceEvolution.range)

    if (! isNan(lnumStockPricePreceding)) {

       /// do something

    }

    lnumStockPricePreceding = lnumStockPrice;

}
```

... is far from pretty but it works as expected, thanks for your
