Hi there, I just want to explain the following bug in the blueprint editor, as you can see in the image below the tooltip of the new variable data type, double, the tooltip is wrong, it is saying that it is a 64 bit floating point number, this is for the integer 64 variable data type.
More details in the image below:
A Double is a floating point number, not an integer; it’s short for Double-precision floating-point.
The 64 bit version of an Integer is typically known as a long in C/C++, but you can find the type in UE as an Integer64. Both tooltips for Double and Integer64 seem to be showing the correct explanation to me.
