HALF_ERRHANDLING_UNDERFLOW_TO_INEXACT

Raise INEXACT exception on underflow. Defining this to 1 (default) causes underflow errors to automatically raise inexact exceptions in addition. These will be raised after any possible handling of the underflow exception.

Note: This will actually cause underflow (and the accompanying inexact) exceptions to be raised only when the result is inexact, while if disabled bare underflow errors will be raised for any (possibly exact) subnormal result.
