x07cac gets the current IEEE exception halting mode.

#include <nag.h>

void	x07cac (Integer exceptionmode[])

The function may be called by the names: x07cac, nag_ieee_get_exception_mode or nag_get_ieee_exception_mode.

x07cac gets the current IEEE exception halting mode for the three common exceptions: overflow, divide-by-zero and invalid operation.

IEEE (2008) Standard for Floating-Point Arithmetic IEEE Standard 754-2008 IEEE, New York.

1: $exceptionmode [3]$ – Integer Output: On exit: each of the three elements of exceptionmode is set to $1$ if the corresponding condition will raise an exception, and is set to $0$ otherwise. $exceptionmode [0]$ concerns floating-point overflow, $exceptionmode [1]$ concerns floating-point division by zero, and $exceptionmode [2]$ concerns floating-point invalid operation.
