+=head2 Handling of underflow and overflow

+VOS does not support automatically mapping overflowed
+floating-point values to +infinity, nor automatically mapping
+underflowed floating-point values to -infinity, unlike many

+floating-point computations that underflow or overflow will
+probably result in SIGFPE. Don't push your luck.
