Summary
The FP_IEEE_ENV_RESUME_ procedure restores the floating-point environment (the rounding mode,
the exception flags, the trap enables, and the denormalization mode) to the values it had before
calling FP_IEEE_ENV_CLEAR_.
NOTE: This procedure is supported in all J-series and H-series RVUs and in G-series RVUs
beginning with G06.06. IEEE floating-point is available on all NB-Series and NS-Series systems,
and on all S-Series systems, except S70000 servers with NSR-G processors.
Syntax for C Programmers
#include <kfpieee.h>
void FP_IEEE_ENV_RESUME_ ( fp_ieee_env savedEnv );
Syntax for TAL Programmers
?SOURCE $SYSTEM.SYSTEM.KFPIEEE
FP_IEEE_ENV_RESUME_ ( savedEnv ); ! i
Parameter
savedEnv
input
INT(32)
The previous floating-point environment that was saved by the last call to FP_IEEE_ENV_CLEAR_.
