float64 is a 64-bit float on all machines. A "32-bit machine" refers
only to the size of its memory address space and the size of the
integer type used for pointers. It has no effect on floating point
types; 32- and 64-bit versions are standard on all supported platforms
though the higher precisions vary significantly from machine to
machine regardless of whether it is 32- or 64-bit.
