+FPmode Option (Enhanced) |
|
|
+FPmode specifies how the run time environment for floating-point operations should be initialized at program start up. By default, modes are as specified by the IEEE floating-point standard: all traps disabled, gradual underflow, and rounding to nearest. See ld(1) for specific values of mode. To dynamically change these settings at run time, refer to fenv(5), fesettrapenable(3M), fesetflushtozero(3M), and fesetround(3M). |
