+optimizations are enabled in the section of code governed by the pragma.
+Effectively ``-ffast-math`` is enabled and ``-ffp-contract=fast``. This pragam
+disables ``-fmath-errno``.

- * ``precise`` Disables optimizations that are not value-safe on
floating-point data, although FP contraction (FMA) is enabled
(``-ffp-contract=on``). This is the default behavior.
+ * ``precise`` Disables optimizations that are not value-safe on
floating-point data, although FP contraction (FMA) is enabled
(``-ffp-contract=on``). This is the default behavior. This value resets
``-fmath-errno`` to its target-dependent default.
* ``strict`` Enables ``-frounding-math`` and
``-ffp-exception-behavior=strict``, and disables contractions (FMA). All of
the ``-ffast-math`` enablements are disabled. Enables ``STDC FENV_ACCESS``: by
default ``FENV_ACCESS`` is disabled. This option setting behaves as though
``#pragma STDC FENV_ACCESS ON`` appeared at the top of the source file.

Did the same for the rest of the text too. Is that OK?
