What benefits has the following?
private double pro;
pro = Double.NaN;
Why not make it
pro = 0.0;
the getter is:
public double getpro() {
if (Double.isNaN(pro))
somemethod();
return pro;
}
Because
NanNstands for “not a number,” it is generally a hint that the number hasn’t been initialized.You could use
pro = 0.0;and that would be fine, too. I think that the issue is more of a style-thing.
