64 bits?

this has bugged me for some time... the value reported on this page for PI is a more precise value that can be held in a 32bit float (3.1415927), but considerably less than a 64bit float.... and leads me to wonder.... is float math being done in 64bits, then being rounded to 32bits? on a related note does anyone have a solid method for extracting the actual float value to text vs the truncation (that I thought was fixed) that happens on string casts? I know that vectors and rotations in a list are not as severely truncated when cast to string, but there still seems to be some rounding going on (looks like ~1 place with casts from lists, and 2 with casts directly.
