When I enter
1.4 x 1 = 1.450000047683716 should be 1.45
1.1 x x = 1.100000023841858 Should be 1.1
1 x 1 = 1 Ok.
I do not think this is normal or maybe it is and there is extremely
good explanation to use setFloatingPointFormat.
Pleas confirm If it's a bug or that I have to specify some sort of
flag/option?
It's not a bug. It's just that floating point variables has never been
a particularly good choice for representing decimal values with great
(or even some kind of) accuracy.
