Given that 5.3.5.3.3 defines a subnormal number indepedent of ISO 60559 
support, should we say

 	... and also y/x is subnormal.

The concept of "nonzero BLOB is too close to zero" only exists in Section 7
18 times for the trigonometric, exponent and logarithmic routines.

Everywhere else, it is called "subnormal" and used 50+ times.
