Warnings

Do not use this option for programs that depend on IEEE standard floating-point arithmetic; different numerical results, premature program termination, or unexpected SIGFPE signals can occur.


Note -

In previous SPARC releases, the -fast macro option included -fnonstd; now it does not. Nonstandard floating-point mode is not initialized by -fast. See the Numerical Computation Guide, ieee_sun(3M).
