Description

The p?lachkieeefunction performs a simple check to make sure that the features of the IEEE standard are implemented. In some implementations, p?lachkieee may not return.

This is a ScaLAPACK internal function and arguments are not checked for unreasonable values.

Input Parameters

rmax

(local).

The overflow threshold(= ?lamch ('O')).

rmin

(local).

The underflow threshold(= ?lamch ('U')).

Output Parameters

isieee

(local).

On exit, isieee = 1 implies that all the features of the IEEE standard that we rely on are implemented. On exit, isieee = 0 implies that some the features of the IEEE standard that we rely on are missing.
