OpenSCAD/CGAL is said to use 'fractional numbers', supposedly without 
data loss, at the price of slow execution and high memory use. However, 
the statement "OpenSCAD can have representation problems with very close 
vertices" is a characteristic for a system representing vertex 
coordinates using ordinary floating point numbers (single or double 
precision). If what you say is true, it may seem users are paying a 
price (slow execution and high memory use) for something (lossless 
computations) that isn't available?
