1 Purpose

x07cac gets the current IEEE exception halting mode.

2 Specification

#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.

3 Description

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

4 References

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

5 Arguments

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.

6 Error Indicators and Warnings

None.

7 Accuracy

Not applicable.

8 Parallelism and Performance

x07cac is not threaded in any implementation.

9 Further Comments

None.

10 Example
