-+Give a warning when a value of type @code{float} is implicitly
-+promoted to @code{double}. CPUs with a 32-bit ``single-precision''
-+floating-point unit implement @code{float} in hardware, but emulate
-+@code{double} in software. On such a machine, doing computations
-+using @code{double} values is much more expensive because of the
-+overhead required for software emulation.
-+
-+It is easy to accidentally do computations with @code{double} because
-+floating-point literals are implicitly of type @code{double}. For
-+example, in:
-+@smallexample
-+@group
-+float area(float radius)
-+@{
-+ return 3.14159 * radius * radius;
-+@}
-+@end group
-+@end smallexample
-+the compiler will perform the entire computation with @code{double}
-+because the floating-point literal is a @code{double}.
