CL Name Style:

1 Purpose

x07cbc sets the current IEEE exception halting mode.

2 Specification

#include <nag.h>
void  x07cbc (const Integer exceptionmode[])
The function may be called by the names: x07cbc, nag_ieee_set_exception_mode or nag_set_ieee_exception_mode.

3 Description

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 Integer Input
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.
