I don't think leaving the stored float format to the
library interferes with this sort of optimization.
The compiler can still do computations using the max
precision fp type it has; the last step for the compiler
would be communicating this result to an external
function supplied by the library authors to generate
a stream of bytes representing the number in the
proprietary format.
