Question

double x = 1; 
double y = 3 * (1.0 / 3); 


x == y

In a powerpoint I am studying, it said the statement is logically questionable. I cannot find out why it is thus, I mean you use == for primitives correct, or is it Logically questionable because doubles are not stored exactly or am I missing something obvious? Thanks

Answer 1

I think you’ve got it: since the data types are doubles, rather than int or Integer, the resulting x and y may not be precisely equal.
