1 Purpose

nag_set_ieee_exception_mode (x07cbc) sets the current IEEE exception halting mode.

2 Specification

#include <nag.h>

#include <nagx07.h>

void	nag_set_ieee_exception_mode (const Integer exceptionmode[])

3 Description

nag_set_ieee_exception_mode (x07cbc) sets 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[ $3$ ] – const IntegerInput: On entry: each of the three elements of exceptionmode must contain any nonzero value if the corresponding condition should raise an exception, and contain $0$ 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

Not applicable.

9 Further Comments

None.

10 Example
