Arguments

1:     exceptionmode3 – Integer arrayInput
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. exceptionmode1 concerns floating-point overflow, exceptionmode2 concerns floating-point division by zero, and exceptionmode3 concerns floating-point invalid operation.

6
Error Indicators and Warnings

None.

7
Accuracy

Not applicable.

8
Parallelism and Performance

x07cbf is not threaded in any implementation.
