1  Purpose

nag_get_ieee_exception_mode (x07cac) gets the current IEEE exception halting mode.

2  Specification

#include <nag.h>
#include <nagx07.h>
void  nag_get_ieee_exception_mode (Integer exceptionmode[])

3  Description

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.

4  References

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

5  Arguments

1:     exceptionmode[3] IntegerOutput
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

nag_get_ieee_exception_mode (x07cac) is not threaded in any implementation.

9  Further Comments

None.

10  Example

See Section 10 in nag_is_finite (x07aac).
