+This option has an effect similar to Java's <Literal>strictfp</Literal>
+modifier: When it is not given, intermediate floating point values can
+have a <Emphasis>greater</Emphasis> precision/range than the final type.
+Generally this is a good thing, but some programs may rely on the exact
+precision/range of <Literal>Float</Literal>/<Literal>Double</Literal>
+values and should use this option for their compilation.
