Warnings

When nonstandard mode is enabled, floating-point arithmetic can produce results that do not conform to the requirements of the IEEE 754 standard.

If you compile one routine with the -fns option, then compile all routines of the program with the –fns option; otherwise, you might get unexpected results.

This option is effective only on SPARC devices, and only if used when compiling the main program. On x86 devices, the option is ignored.

Use of the –fns=yes (or -fns) option might generate the following message if your program experiences a floating-point error normally managed by the IEEE floating-point trap handlers:
