double float

If you now enter a decimal, such as "2454323586.468495308", in the "floating point" or "vector" of the geometric node, the number will become inaccurate because of the digit limit. To solve this problem, I need to create a new node group, enter the required numbers in different input boxes, that is, separate my floating-point numbers, and then add and multiply. Because we are working on a bridge project, the drawings given by customers are in tens of kilometers and are required to be accurate to millimeters, so I have to build a complex set of nodes for a precise coordinate.

If Blender natively supports "double" or "float function", maybe all of this will be very simple. I don't like drivers because they are easy to lose when copying assets.
