Where is the TSizeF type in the Types.pp

[dmitryb]

I'm wondering why there is a type declaration in the Types.pp file:
TSize, TPoint, TRect
TPointF, TRectF

But there is no TSizeF type.
Is it declared in some other file?
I didn't find where.

Why would you expect that? a type has a fixed size expressed in one of the integer types. types are not size 1.0000345678 size.

There will be a Types.TSizeF in the upcoming FPC 3.2.4.

Why wouldn't there be a floating point size? After all a floating point rectangle can start at e.g. (1/2), but end at (2.3/2.4) which would make its size (1.3/0.4). It's simply a logical extension of what TRectF provides.

For example.
In a graphical resizing animation, the animation looks smoother if it is drawn based on more precise floating point values ​​at intermediate points than based on integer values.

I think Thaddy simply mistook "a type called  TSizeF" for "a type with a floating-point size".  SizeOf  will of course always return an integer - for very fundamental reasons that every programmer should know. Personally I've never seen any who struggle with this, but I've seen plenty who might want to work on their reading skills

Thanks to dmitryb for asking the question because I wondered about that myself as well.

Thank you very much.

Now I can finally get rid of my own half-baked definition (well, whenever 3.2.4 is released that is) :-)

Thaddy mistaking things is his usually modus operandi after all... 😅

Yes, but not always.....
